Kiffin is a very good OC. I wouldn't discount him. His dad wasn't a very good HC either but we all know how good he is as a DC.
FWIW, I believe there is a "Saban factor" to recruit rankings. He has earned it by being accurate in his recruit evals. When sites award 5* it is as much about "confidence" as quality. When Saban recruits a guy who appears to have top shelf measurables... the recruiting sites take notice. That gives them confidence.
Saban has the biggest impact on how the graders grade but Miles and others have an impact too. The guy who IMO has done the most to not deserve to have that factor is Meyer. He has a good record of winning with talent recruited by others but not in finding the right players himself. Usually his guys fail on character... kind of predictable considering his difficulty with being trustworthy or honest.
If/when Jones' players get it done on the field, his recruits will get more love.
