Yeah, Brewer is not going to make it on the 53, and I'm not sure they'll keep him even on the PS. Not good so far.
The Evans thing is kind of interesting. I think they keep playing him at OG not because that's his best position (which is RT), but because it's his weakest and they want him to be the #1 RT/OG game day replacement.

The Oline is an interesting 53 decision as well as suited up game day players decision. Ideally you only dress 7 OL. But they must be multi-faceted to do that. Unless they make a move, they're either going to dress 8 (with Shelton the likely 8th), or they're going to dress 7 with the idea that if Allen gets injured, Corbett moves over and Evans comes in. As it stands, Noteboom and Evans are the game day guys, but Anchrum might be making a case for himself to replace Evans.
