I'm fine will all of this except the idea that "ideally we cut Connolly". I would think he is worth keeping as a Game Day backup for the 3 interior line positions.
I'm not sure what to do about the C and back up OL position. You are correct, that Connolly is very valuable because we know he could capably back up at 3 positions. However, you can't justify paying a backup, even one as versatile as Connolly, that starter's cap number.
It might just come down to making a choice. IIRC, In 2011 Connolly did an admirable job pass blocking but wasn't much of a run blocker starting at C. Wendell, on the other hand, has excelled at run blocking and shown weakness in pass blocking last year. You also have to consider that Wendell statistically had a great year in 2012 (top 10), but had a poorer year last season.
In the Draft, Martin in supposedly the best C option. I've seen him be rated as high as a low #1, and as low as the 6th in one mock. There's a possibility he might be there at 62, but if he and Niklas are both there, who do you go for. Richburg is the 2nd rated C, and who knows where he'll go. In an ideal world to us in the 3rd AFTER we've gotten our DT and TE. Both these kids are projected to be starting C's in the league. The question is can they be upgrades at center THIS year. I am not sure.
Here are 3 possible scenarios. Let me know what you think
1. The Pats sign a swing T to a contract that will create a $1.5MM cap number. Ideally it will be Svitek, but there are others who seem capable. We move Connolly back to C, and Cannon to RG, with the hope that one of the unknowns like Josh Kline can wind up being a capable back up. Now we don't need to bring in a FA center, and any C we draft will have the luxury of not having to start right away.
2. We bring back Wendell and release Connolly. Again we move Cannon to RG, sign the swing T, and draft the rookie C. This is the scenario that not only creates the most cap room, but could create the best run blocking OL in the league. On the other hand it carries the risk of not having a proven interior OL back up, and a perceived weakness in pass protection at the C position.
I say"perceived", because only coaching staff really knows how much responsibility of any weakness of the interior line's pass defense was actually Wendell's
3. I don't know how happy I'd be with this one, but it is an option. In this one we restructure Connolly and pay him as a back up. Move Cannon to RG and pass on Wendell. Then sign the back up swing guy and draft a C in the 2nd or 3rd rounds and hope to hell he can be an instant upgrade over Wendell and Connolly. This one leaves us with outstanding experienced depth all across the OL, but creates a huge question mark at Center.
Bottom Line: At this point I have a clue which would be the best plan, or even if there aren't better ones.
