There are definitely significant pros/cons to both sides.
He will be marketed as a Tampa 2 style player given his size and speed (I can't remember if he struggled in coverage, I think he did). If he stays, he could find a definite role in a very good transition period as a Tampa 2 LB. Again, given Monte installs the Tennessee 2 (step) at the Hill.
Or he could chance it and go Pro and not risk being injured. He might take a page from Foster's book and not play his cards poorly.
That said, I think it would be a very poor choice for him to leave.
