First, I don't expect these guys to be 14 sacks DE's anymore. That being said, I think there is value to these guys. The Pats pass rush will live and die on the development of Chandler Jones. a 2nd pass rusher couldnt hurt this team and would provide injury insurance if Jones goes down. Both are getting up there in age, but I still think each could have the same type of impact Andre Carter had. I also think this team is lacking veteran leadership on the defensive side. Gregory and VW are the only impact players on the defense that are at least 30. I think a Veteran presence could do this team some good.
Osi is the guy I would prefer most. I think his postseason experience, which has largely been success, can do the team some good. Umenyiora has played in the underdog role and has largely thrived in that. I think he can help bring an attitude to the team come playoff time. Same thing with Freeney, but to a lesser extent. I think they can be effective pass rush specialists.
Salary expectations is probably the biggest question with these two. Cliff Avril and Paul Kruger will be the "prized" pass rushers in this FA class. I don't expect either guy to get that type of contract Mario got last season.
John Abraham got a 3 year 16.5 million contract last offseason. This was coming off back to back seasons in which he had 13 and 9.5 sacks.
Freeney the last two seasons has had 8.5 and 5, while Osi is at 9 and 6.
I think both can be had at john Abraham's contract, but probably less. I'd be surprised if Freeney got anything more than a two year deal, Osi, I can see 2-3 years for him.
Osi might be seeking a starting job. I'm not sure. He probably would have stayed in NYG if he was okay coming off the bench.
Freeney is coming off an ineffective season playing in the 3-4. He's older than Osi and I think will come for a cheaper price. He might also be okay with being a pass rush specialist.
I think the Pats should seriously consider one of the two. Both are the veteran type of FA's that BB likes to target. Hopefully they can work out like a Rodney Harrison as opposed to a Ochocinco.
