Alvin's a RB. Its natural for him to be my first hit because running back is the easiest position to transition from college to the NFL. QB, WR, DE, and CB all take longer.
Just wait. Josh Dobbs, Corey Davis, Myles Garrett, and Cam Sutton will follow suit very soon. All 4 are as talented as Alvin. They just play positions that require a little more development in the pros.
When they hit their prime, you're looking at guys who will be the best at their positions. Josh Dobbs will be the best QB in the NFL. Corey Davis will be the best WR in the NFL. And Myles Garrett will be the best DE in the NFL. Cam Sutton will be among the top 3 CBs. And Alvin Kamara will be a top 2 RB in the NFL.
