I'd pump the brakes on Mayfield being much of a factor next season. Reasons why:
1. Super young. Just turned 18 last month.
2. Not a super skilled guy. Not a greater shooter. Potential is largely around athleticism.
3. Is described as a hybrid-4 with a long-term outlook that could see him develop into a wing. Doesn't have the skills to play wing yet, offensively.
A 6'7 (even if he does have a 7'1 wingspan) 18 year old with limited skills, despite good athleticism, is going to have a hard time fighting other 4's in the SEC. IMO.
