I actually think this is an interesting topic.
Looks like Noteboom should make it back and play LT. AJ needs to start somewhere so he'll play OG on either side. If Edwards is healthy and can come back on a cheap contract he could be at LG again. He was our starter there for two SBs. Allen and Shelton should fight it out at center. At RG, we would have AJ, the runner up at center (Shelton) Ancrum, and Bruss. At RT is Havs. On paper, we should look pretty good and actually deep. I would resign Nseche as he played well at LT and LG last year and shouldn't cost a ton to keep. Edwards did suffer two concussions and may hang them up.
But, he is still pretty young and is very experienced in our blocking scheme. I know he gets tossed against the Niners, but many guards do.
