http://msn.foxsports.com/nfl/story/5834838 13. Patriots Bill Belichick loves to play chess with his hybrid 3-4 defense, but he may be one piece short if one of his veterans gets hurt. Tedy Bruschi became the inspirational story of the decade last season when he returned from a stroke and played well down the stretch. But Bruschi suffered a calf injury late in the year and turned 33 a month ago. Mike Vrabel has done it all for Bill Belichick Ă˘â‚¬â€ť he's been a pass rush specialist, an outside linebacker, and inside linebacker, and a tight end Ă˘â‚¬â€ť but he is also getting old and has lost some of his initial quickness. Monty Beisel is adequate between the tackles, but he's mistake prone and awful in coverage. Roosevelt Colvin is a top pass rusher who plays like a defensive end. Tully Banta-Cain is Diet Colvin. Chad Brown was recently re-signed, giving the Patriots another veteran defender with a long injury history. There's very little youth here; last year's fifth-round pick Ryan Claridge has already been released, and undrafted rookie Freddie Roach will probably make the team as the only linebacker with less than three years of experience.
