Wasn't a fan of Chief's, but truth be told, he's a pretty good DC when he's got the horses. I have to wonder if the 3rd and Chavis wasn't more about lack of talent rather than scheme? If you can't get heat on the qb and/or you don't have good cover men, do you really want to get up and try to press? How confident do you think Wilcox is about bringing...and no offense intended to the young man...Teague up to play press on a WR with some speed? Nah...you play soft and hope the qb makes a mistake or the pressure gets to him.
Talent will make a coach look good and a lack of talent will get him fired. It's all about getting the Jimmys and the Joes.
