best offensive prospect = saquan barkley and sam darnold
best defensive prospect = minkah fitzpatrick and derwin james
No. The best 2 offensive prospects are Saquon Barkley and Antonio Callaway (aka baby Sterling Sharpe). And the 2 best defensive prospects are Derwin James and Arden Key (aka baby Simeon Rice).
(1) Saquon Barkley is the best RB prospect since Adrian Peterson. He's like a better version of Ezekiel Elliott.
(2) Derwin James is the best safety prospect since Sean Taylor. He's better than Jamal Adams and Eric Berry (who went top 10 in the last 10 years).
(3) Antonio Callaway is a clone of Sterling Sharpe (who would've been a hall of famer if not for a neck injury).
(4) Arden Key is a clone of Simeon Rice (who is a borderline hall of famer).
The talent at the top of the 2018 class is insane. I don't think it has the depth of 2017 though. The first round in 2018 is where all the action will be.
