Good questions.
DE: I think we keep 5, because Maybin's contribution will be limited to obvious passing situations early on. Either Ellis or Bryan will go, I think it'll be Ellis. Just my gut, but I think the reports on his strong performance are largely exaggerated. Yes he improved from last year, but that's not saying very much.
S: Easy, Simpson and Wendling are gone.
RB: Very trick, especially considering that Lynch will miss the first 3 games. If they cut anyone, it'll be Oman or Rhodes. I think that they keep all 5.
TE: None of them are legitimate starters, so you definitely cut one. Fine and Stupar are neck and neck. I say it's Fine that get's cut.
