I'm a Canty fan. I thought he was solid player for the Cowboys who did his job, mostly, although he'd tend to disappear in games against the run.
Having said that, Igor has not only matched the job that Canty did in Dallas ( in the 8 games he's played so far ), but he's surpassed it. Some of you may not have noticed it, but we are better against the run than we were last year and alot of the credit goes to Igor along with Spears, Bowens, and Hatcher.
Off the top of my head, I don't know if the stats back me up, but from plain eye sight, we are a heck of alot more consistent in that department. Since the first game against Tampa, were we didn't respect their running game and paid for it, other than two medium size plays, one by the Giants ( Jacobs - 31 yards ) and the other one by the Panthers ( Williams - 17 yards ) we haven't allowed jack.
We've allowed 823 yards rushing and 3 TDs in the entire season. Of those 174 yards and 2 TDs came in the Tampa game. That means in 7 games, the Cowboys have allowed 649 yards and 1 TD, including the 2 longest run previously mentioned.
Igor, so far, has been an outright steal. This off season, overall so far, has been simply outstanding in terms of producers: Sensanbaugh, Igor, and Brooking.
