I’m betting that Sanders comes back in a couple of weeks, the O line chemistry has been good the first 2 weeks and putting Sanders out now wouldn’t be smart. You risk disrupting the good chemistry, you risk reinjury, and starting a freshman for his first game against probably one of the best teams in the country might not be smart for him or the team.
I personally don’t expect McCoy will ever play this year, professional FB players are usually out an entire year with an ACL reconstruction. Why would you expect a college player to come back sooner? I think the bigger question is : WILL HE TAKE A REDSHIRT YR? whether that will improve a first team AA future draft prospect or hurt him might be up for debate and how well his knee is doing and rehab is doing. I would be surprised to actually see him play this year, maybe for the bowl game if there is one.
I don’t know anything about Gibson and what injury he has
