I talked about the importance of re-signing Bulaga in this post:
https://www.packerforum.com/threads/we-hang-onto-our-own.58491/#post-599281
Why re-sign him? Because he’s young and will be entering his prime. Because I don’t think Barclay or Tretter are adequate starters at RT. Because he was an important part of what I consider the best Packers OL in a decade. Because being in sync and continuity is more important on the OL than any other unit (I think the Grantland article I quoted and cited in that post explains it well.) Because I want the Packers to be able to use their entire playbook and not have to compensate for having to help a RT. Because I want to be able to spend a few more seasons without the constant complaining (mostly justified IMO) about the Packers OL as in the not very distant past. Because unless he demands to be paid like a LT, they can afford him, cap- and cash-wise.
Because some of us have noticed Rodgers suffered injuries in the last two seasons and even if you don’t want to hear about it, it’s a real concern (and as stated above I don’t want them to have to “compensate”). While re-signing Bulaga doesn’t guarantee Rodgers’ health, the best bet to keep him healthy is having a good to great OL in front of him and Bulaga gives the Packers the best chance to do that.
Sign him at any price? Of course not. Cobb is more important? OK, but I still want them to keep Bulaga. McGinn says he had the fewest “bad” runs on the OL last season and, “(b)egan really punishing defenders from about midseason on". And as I’ve posted before, if you’re a draft and develop team, you have to keep the core players you’ve drafted and developed. They spent a first round choice on him and they've invested a lot of time and money in developing him. He fits like a glove on the OL and in the locker room. I hope he's reasonable and wants to stay.
