I have to assume that Gonzo will be used for the big, tall WRs that are so prevalent in the NFL these days, and not used as an all-purpose DB who has to go against the tiny, quick, smurfs. I assume that the defensive coaching crew will scheme things so that Gonzo will only have to cover the big guys. That being said, from what I saw in Training Camp, Gonzo could go step for step with anyone (although I don't remember him going up against Douglas--no one could cover DD that I saw), but he did not always make a good play on the ball...in other words he never seemed to be badly beat, but sometimes did not make the play even though he had good coverage. BTW, I saw Gonzo cover Brenden Schooler like a blanket (when other DBs could not) in punt(?) coverage.
Anyway, having Jack Jones in the clear is a huge development for this team. He was the best CB I saw on the field at Training Camp (Jon Jones was not on the field). This is going to be a wicked tough defense. Expect the Patriots to try to play ball control offense; ball control offense only works when the defense is playing wicked tough.
Another thing I saw in training camp is that the defense has an attitude. They know they are good and take a lot of pride in their play.
