The analysis I have seen shows that if a mid round pick stays another year in college and moves to the first round it results almost always in more money over a career. Simple comparison of two strategies and the current NIL situation adds weight to the stay another year in college.
Not sure why he’d come back. He’s already proven that he can play and there’s always the chance of another injury. I’d welcome him with open arms but if he asked my advice I’d tell him to go to the NFL.
