I was asked this question a few weeks ago, and this person was talking about the absence of a running back having dominated the league in rushing yards. This became very apparent when Jon Cornish missed at least six games and is still within 200 yards of the rushing leader with his 587 yards to date. Lets talk about some of the factors involved and what has changed. I believe there are three reasons for the change; four designated imports on the roster, talented non-import running backs and running QBs. Lets state the obvious, in every level of football, you must be able to run the football to have a balanced, efficient offense that can handle all the situations that you face throughout the football season. I have coached or coordinated four rushing leaders in the CFL and I believe in running the football. Michael Jenkins (2001), Charles Roberts (2003), Troy Davis (2004) and Fred Reid (2011) all were talented backs who were able to make the most of their opportunities. As the league evolves, you can see one-tailback offenses start to evolve also to spread the wealth, per se. Obviously, injuries can be a factor for a lack of productivity in running backs as they tend to have injuries at times and will have to miss games. As noted earlier, Jon Cornish has missed a great deal of this season and it has affected his rushing totals. But the biggest reason that I believe rushing numbers are down for the backs are the roster and specifically, how many designated imports are on rosters this year. A Designated Import is an International (Import) that can play freely on all special teams and can replace only another International (Import). Long story short is that for teams starting seven Non Imports, the DIs can replace another import but not a non-import. This year, the DIs has increased by one for a total of four on the roster. So you have four players that can play all special teams and also replace other Imports that are on the roster. When I first came into the League in the early 2000s, there was only one DI. It eventually went to a second and finally up to a third until the fourth DI this season. When you had only two DIs, one was usually a kick returner and one was a defensive player. It was difficult to carry a backup running back that was an import unless he was the returner. That is how many running backs earned their roster spots originally. In 2001, Hall of Famer Charles Roberts was on the roster as a DI who returned kick-offs and punts and spelled the starter Eric Blount. The rosters did not allow for a very talented import running back to be on the roster just as a backup. Cut to this year, where with four DIs, you can have two back-ups on offence and defence. One of those usually is also a returner and backup as in Brandon Banks in Hamilton, and the other three can be utilized on the roster as a backup and in situational packages. One of the most important things to understand with this roster size now is that you have the ability to plan and practice expecting to have the DI available to you if you are a coordinator because of the four spots. In previous years with less DIs, often the DI would be decided depending on the health status of your roster. For example, you may have to dress an Import DI receiver because one of your starting import receivers is banged up and may not play the whole game. If you normally used a DI running back, you would have to make the switch and take the DI running back off the roster and replace him with DI wide receiver. Nowadays, you can have both on the roster and still be able to gameplan for the roster spot as a DI running back. So how does all that relate to running back rushing yards? Teams are allowed to break up the rushing job to more than one back and are able to build packages with two tailbacks in the game at the same time. Edmonton has utilized this by having Kendial Lawrence and Tyler Thomas on the roster. They can split carries as well as be in the game at the same time and have plays designed for each other. Lawrence is 11th in rushing and Thomas is 16th. Add their rushing yards together and they would lead the CFL in rushing. Edmonton also has Jon White, who has also rushed for 334 yards this season but is on the six-game injured list. Saskatchewan also has had success with using multiple import running backs on the roster. Anthony Allen leads the Riders with 593 yards which puts him third in rushing in the CFL. Will Ford is sixth in rushing with 425 yards and is able to be part of a 1-2 punch that the Riders rushing attack will hit defences with. Toronto has utilized several different backfield combinations this season but normally carry two import running backs. Curtis Steele is eighth in rushing with 437 yards and a healthy Steve Slaton is starting to come on with 224 yards so far. Montreal is fun to watch with Brandon Whitaker, who leads the CFL with 695 yards and they can also line up with Tyrell Sutton in the backfield. Sutton gets the opportunity to prove his worth and not have to wait for an injury to the starter to be on the roster. Talented non-imports are another reason for individual rushing numbers being down. I dont care what nationality you are, if you are talented, you will touch the football. Jerome Messam is part of the three-headed monster of the Riders run game and he has 326 yards this season. He is a bruising runner and a great change up for the Riders. Matt Walter has had some opportunities to play this year, allowing Calgary not to have to disrupt their roster when Cornish was hurt. Andrew Harris status as a non-import starter allows depth at other spots and can allow for a running back to be an import on the roster. Rushing QBs and packages designed for the QB as a running back have emerged the past few seasons to create extra packages and schemes that the defence must work on. Pat White in Edmonton has 26 rushes for 113 yards and his offensive package forces defences to take valuable time from practice to prepare for his package. Hamilton also has utilized a package for QB Dan Lefevour the past two seasons. These QB packages create problems for defences as the quarterback is the ball carrier and the defences are not used to the quarterback being a ball carrier and also there is a numbers advantage when the QB is the primary ball carrier. It is important that these QB packages have throws built in to make sure it is not 100 per cent run or else the defence will load the box to stop the run. The QB running game packages will take away reps for the starting tailback because many times the QB carries the ball in these packages. Although rushing numbers may be down, it is a great thing to be able to have more players on the roster to create excitement and be able to have multiple rushing football players. The years of the 2,000-yard backs may be over, but the ability to keep more players involved is certainly fun to watch. Jorge Alfaro Jersey .

Well, exactly.One — Williams — was signed off the practice squad five days before the Jets played at Kansas City. The other — Thomas — was signed a month ago as a free agent and made his Jets debut against the Chiefs. Its not exactly Darrelle Revis and Antonio Cromartie patrolling the secondary, as coach Rex Ryan had back there for a few years.Its also one of the biggest criticisms of general manager John Idzik, that he didnt sufficiently bolster the cornerback spot through free agency and the draft.Last week, defensive co-ordinator Dennis Thurman half-jokingly — maybe — said: I know a couple of their numbers.And, just when the Jets didnt think things could get worse, Ben Roethlisberger, coming off two straight games with six touchdown passes, is coming to town with the Pittsburgh Steelers.Scary doesnt come to mind, Ryan said Thursday when asked of the task his secondary is facing. Yeah, youre concerned, but its more about what youre facing. The guys we have in the building, theres some good players over there that we have and its the collective effort of all 11. It doesnt just fall on whos playing right corner or left corner.We have some guys that can play. They all can play.And, they all have. Ryan and Thurman have used several combinations at cornerback throughout the season because of injuries, inconsistency or ineffectiveness. Ryan also acknowledged that he has played much more zone coverage than man-to-man, which is usually a constant with his defences.When Dee Milliner went down with a high ankle sprain during training camp and third-round draft pick Dexter McDougle was lost for the season with a knee injury, safety Antonio Allen was switched to cornerback in what was called an experiment by Thurman.It lasted more than halfway through the season.Milliner was lost for the year with a torn right Achilles tendon and free-agent addition Dimitri Patterson was cut after he was first suspended for an unexcused absence before a preseason game. So, Allen ended up starting opposite Darrin Walls on opening day. After weeks of struggles, though, Ryan hinted that Allen might be moving back to safety for the rest of the season.You can compplain about it or you could just be quiet and go to work as usual, Allen said.dddddddddddd Thats what I came and did. I did my best. I probably gave up a touchdown every game but, hey, that was the sacrifice that I was willing to give up.Its difficult to blame Allen, who showed promise last season at safety before being forced into the position switch.He has tried to do everything that we have asked him to do, Thurman said.Ryan acknowledged that the Jets held an in-season competition at cornerback last week, with the reward being playing time. Williams, despite being a newcomer, outperformed everyone and earned the start. The undrafted rookie out of North Dakota State spent the first month of the season on Houstons practice squad, was released at the end of September — and is now looking at potentially making his second straight start for the Jets.He has picked up the defence fairly well, Thurman said. He has had a couple of breakdowns, but for the most part he went out and competed and I thought he fared pretty well for his first start. Well give him more playing time.But it remains to be seen who might be on the opposite side of Williams. It appears Walls, dealing with a calf issue, wont play for the second consecutive game.So, it could be Philip Adams, who has started one other game at cornerback and has the Jets only interception this season. Or, Kyle Wilson, a first-round pick in 2010 who has been plugged in as the regular nickel back. Or, perhaps Thomas, who had two tackles and a pass defenced against the Chiefs.At times, Phillip has done a good job, Ryan said. You had last week with Josh Thomas and Williams. They havent been with us the whole time, but theyve been with us long enough. They know what we do. ... Were confident in our guys.NOTES: WR Jeremy Kerley missed practice because of an unspecified personal reason, and Ryan said Kerley also will likely miss Fridays session but is expected to play Sunday. ... DLs Muhammad Wilkerson and Sheldon Richardson and RT Breno Giacomini all returned to practice after missing Wednesday with illnesses. ... The embattled Ryan on the Jets being scheduled to play the Miami Dolphins in London next season: Ill say the obvious: As long as Im on that plane, itll be a great trip. Im looking forward to it.___AP NFL website: www.pro32.ap.org and www.twitter.com/AP_NFL ' ' '
