It all depends. Sam montgomery for LSU tore his acl and came back better than ever. Cyrus tore his much later in the season and we aren't asking questions about his readiness to play. I know he isn't doing jump cuts but haven't heard one question of whether he will be ready.
If Hart was at 100% he'd be starting with EL out no question being his second year. No way he is 100% at least psychologically with his running style. Dee Hart came in as one of if not the best HS RB in the country, and he looked the part before the injury so I am told by my secret yet well known source over a beer on the strip last year. Dee having a good a-day game yet somewhat unremarkable is not Hart at 100%.
When I played High School ball I was effected en entire season with a strained back, can't imagine a year removed from a complete knee tear being 100%. We have come a long way with folks like Dr. Andrews, but the body is still the body and the mind is still the mind when healing. This thread is teaching us about the severity of something many had thought was somewhat minor in Turf Toe.
Not being 100% is frustrating when injuries are mum unless you are out due to it. You want to let everyone know that you're hurting but it could make you a marked man, especially a d-back.
