I always liked Good better at RB/WR than trying to experiment with him playing CB in college.
Does he have good physical traits, sure. But, Corner in today's game are so much more important than they may have ever been due to rule changes making it **** near impossible for CB's to put hands on WR's down the field.
Meaning, if your not a natural Corner it's going to be very difficult to be taught how to play the game so late in your football career & trust me, learning Corner on the fly in college could potentially be brutal if you're not an exceptional talent to make up for what you lack in experience & technique.
The fact is he's not a CB, could he become one? Possibly, but it's not likely he would ever develop into a high level ACC caliber corner & the last thing we need is a DB that can't cover. No sense in wasting his athleticism, kid should've been recruited from the jump as an ATH, RB/WR/KR/PR.
