I think it's best to assume he's never going to play a meaningful snap at CU. If he does great, but I think it's a long shot. Wish the kid all the best and a full recovery.
Have to give him credit, he has worked his butt off and done everything he can to come back.
Almost have to wonder if they give him this year then sit down with the specialist and look at if it is best for him and the program to give him a medical retirement and free up his scholarship for somebody else.
He would still get to complete his degree and would have access to full medical and academic support.
I'm certainly not a doctor but when do they have to start seriously asking how much longer they keep trying.
