The weird thing about him starting out at WR is that there is a clearer path to immediate PT at DB, especially safety. I'd like to see him switch over to DB sooner than later.
The issue is learning curve & impact...
Sure, he could play DB early on, but it's much more difficult position to play as a Freshman & he's not starting over any of the CB's.
If you put him at FS, we have the same problem we have now which is inexperience at that spot, would you want Quan & Deejay as the starting Safety's?
At WR, he can go in from day 1 and get plays where he has an immediate impact on the field, the learning curve is much smaller at WR than it is at DB, plus he can be used in multiple packages.
At RB he simply won't see the field, he doesn't have a big enough frame & he'd essentially be splitting carries with Burns.
Only way it would work is if he ran a wildcat style on special packages, which I'm not so sure Richt would run often enough justify moving Deejay to RB.
His upside in the Long run might be best at Safety, but based on how highly Richt thinks of him & the fact he's an EE means he's not going to redshirt this season, therefore it seems WR is the best option for him to see meaningful snaps come September.
