We don't know. He was pretty solid as a rookie, started off year 2 very shaky, got a little better, then had a really bad injury. Injury has carried over to Year 3... so we really haven't seen enough IMO.
he's played ONE snap on ST this year, not good return on a R1 pick... but I'd put that on injury luck, not on Gute. I don't think Stokes had a concerning injury history coming out of college. Also: injuries pretty much end or derail every player's career... and if it ain't injuries, it's age (or suckitude).
