Even if Reiff isn't seriously injured, with McDermott sliding down and Anderson MIA, they needed another OT. They gave Steuber every chance to prove himself and all he proved was that he wasn't ready for the NFL.
Brown, Strange, Onwenu, Andrews, Mafi, Sow, Reiff (if okay), and now Wheatley make 8. Have to think Ferentz if he backup center unless Andrews showed more than we saw in the games, so I'd guess Russey, Hines, McDermott, and Andrews on the PS.
I'm kind of bummed about losing Pierre Strong, though, but JJ deserves a spot just because he's so much fun to watch. If they keep four RBs, will it be Harris, Monty, or someone yet to be claimed, I wonder?
