Hopefully he will be. I know of several players over the years out here [soCAL] that never came back in the predicted timeframe. It always seemed to take longer.
Are you speaking in reference to his specific injury, or just generally?
As another poster mentioned, it's going to take some time for him to get back in football shape, so that's another reason to keep him out this year.
That said, from what he showed his freshman season, if he keeps developing at an upward trajectory there's no reason he won't be playing on Sundays. So I'm not sure you redshirt him if he can have a positive impact on the team this year. You might not have him for 4-5 years anyway.
