Belichick on Warren, Burgess

On a conference call this afternoon, Bill Belichick addressed the Patriots' roster moves -- placing veteran defensive end Ty Warren on season-ending injured reserve and reinstating Derrick Burgess to the active roster.

"It's a tough break for Ty, but we have to move on," Belichick said. "He's missed quite a bit of time the last couple of years. We've had to deal with that anyway. It's unfortunate, but unfortunately that's part of the game. We'll just move ahead."

Belichick praised Warren's projected replacement, Gerard Warren, saying he believes he will help the Patriots this season.

As for Burgess, Belichick said he reported Friday morning and passed his physical and conditioning test. He called him "ready to go" and described him as a “very knowledgeable pass rusher.”

“He has a good understanding of his opponents, pass-rush technique, and how to defeat blockers and how specifically to defeat individual blockers based on their strengths and weaknesses and how he matches up against them,” he said.

“He played primarily in a 4-3 defense in Philadelphia and Oakland [as an end], and in our defense he played some of that position but also some as a 3-4 outside linebacker type. That’s a little different compared to what he has done. I think this year, based on the spring and the workouts we had in May and June, I think he’s really a lot further ahead in understanding what we do and our terminology and techniques and so forth than he was at this time last year.

“Derrick is really a pretty versatile player. I think he can do some different things and he can do them pretty well. We’ll build on what we did in the spring and see where it goes.”
