The OLB spots are really tough for me to judge right now. I don't think there is a lock for the 53 man roster outside of Banta Cain.
Cunningham- He's a lock to not get cut, but is he a lock to make the 53? With his current injury, the Patriots could put him on IR. The Pats have put young guys on IR with relatively minor injuries in the past. If the Pats don't view Cunningham as ready to contribute as a rooke, they could go that route again. That's really just wild speculation on my part though, as I think Cunningham is the 2nd most likely guy to be on the roster at OLB behind TBC. The big question is whether or not he's active on gamedays.
Woods- Hasn't shown much as a base defender, but has the best size of any of our OLB candidates as well as the most experience in the defense. How much does that matter if he's not effective on the field? Where he has been effective is on special teams and with most/all of the Patriots veteran special teamers in a battle to make the roster, I have to believe the Pats will keep a minimum of one of their special teams leaders from past season. My own opinion is that Woods offers the best combination of base down talent and special teams ability out of the group that includes Woods, Aiken, Alexander, and Slater.
Ninkovich- IMHO, he was better at OLB than Woods. That said, he doesn't appear to be the answer as a starter and is not an elite special teams player. His opportunity to make the team is to carve out a role on defense.
Burgess- I am torn on whether I expect Burgess to make the team or not. The fact that the Patriots are even allowing him to come to camp and never closed the door on him during the past two weeks tells me they want him back. On the other hand, I wouldn't be surprised to see the Patriots cut him or for Burgess to decide after a week or two that he really doesn't want to play football any more. My expectations for Burgess have significantly diminished after he contemplated retirement. Once guys do that, they usually don't play at a high level again unless they are Favre.
Murrell- No idea what to expect from him. The Jets didn't make a real push to keep him and I don't know enough about his special teams ability to say whether or not he's a standout in that area. Starting ahead of Ninkovich and Woods in the preseason has to mean something, but I am not sure what.
I wouldn't be surprised to see the Pats keep only 4 OLB's and use Guyton or Spikes outside in certain packages.
