He's coming back. Feel free to bookmark this and come back to it in a week (which is when the deadline for early entry declaration is).
That said him leaving early isn't as crazy as some of you think. Josh Buchanan, who has a good track record of projecting NFL draft picks at the FCS level, had him with a 4th round grade (link) which is pretty good. A lot of underclassmen have left early and been picked later than that or not at all.
