Give him a year to prove himself when healthy. His INT's will be down, but I don't think they utilized him well. They could use him on offense. They could use him on punt returns and kick returns (balance it out with Sproles).
Yeah I'd probably give him a pass on the 0 INT's this season then. Doesn't really make sense to trade a guy that had such a huge impact 2 years ago, and then didn't do great while playing injured...
He had two INT's in one game, that was it. In general, he regressed this year, but its hard to improve when your not moving 100% and your not practicing.
Using interceptions to gauge the play of a CB is a mistake anyway....if a guy is good, offenses stay away and there just aren't opportunities....I am not suggesting that is what happened to Cromarties numbers, but I am sure it contributed....
