So far I've heard negatives about Bruss, AJ, and now Shelton. We needed to hit on one or more of them. At least Anchrum seems to be making it.
I don't know that this is that big of a deal. People have been beating the drum on Bruss but he just is what he is at this point... stop trying to make "fetch" happen. Give him another year and then we can see where he's at but he was always just going to be a depth piece this year and not even 1st guard off the bench. If Noteboom beats out AJ, great! His issue has been health. He's not a roadgrader but he can do some really nice above average LT things. AJ will be the swing tackle and continue to develop, that's good enough (given Noteboom's history, AJ will play at some point this season).
I will say, I had my biases towards Shelton at C as he offered the more physical presence but if Allen beats him out the benefit there is Shelton is an amazing swing C/G who provides great depth and will be the first offensive lineman off the bench (or maybe AJ) outside of anything happening at tackle.
Depth is heads and tales better than last year.
Far more important this year than probably what the line combination will be is the health of the line and the ability for whatever starters we end up with to all play together for as many games as possible.
This will not be a dominate line... but with health it will be in the top half of the league.
