He would have to do something amazing to be 3rd round.
In order to hit the 4th - 5th round he'd have to be a Top 10 back based upon past drafts.
As of now he isn't top 25..

The NFL has been waiting on this class of RB's for 2 years now - dubbing this the Draft of the Running Back.
I dont want to poo poo our own guy but I'd hate to miss out on him next year if he is a 7th rounder or UFA.
Late round and UFA's almost always have to be special teams contributors along with their regular positions to stick. I suppose Boom could be a KR..?
He is ranked higher on a few watch lists for 2018.
