We should only be taking 1 RB in 2020 - Don Chaney Jr, and 1 RB in 2021 - Amari Daniels.
Next yr we will be returning AT LEAST 5 RB/FBs - Deejay Dallas, Lorenzo Lingard, Robert Burns, Cam'ron Davis, Realus George. (Gray graduates, atkins doesn't get his scholarship renewed, and Homer declares for draft like he should).
Then we will be adding 2+ RBs (2 pure RBs, and an athlete or two) - Crowley will be in the class. One of Trey Sanders or Noah Cain has a spot guaranteed, though they're a tough pull. Daniel Carter imo has the 2nd spot of Sanders/Cain don't commit. And then after them McIntosh and Richards are athletes and absbolutely takes (with McIntosh probably wanting to start as a RB, and Richards likely as a WR).
So with the at least 5 returning, and the at least 2-3 being added from the 2019 class, next year (2019 season) we will have 8 RB/FBs on the roster. And out of ALL them, only Deejay Dallas would be at risk of declaring early after the season. So for the 2020 class we'd only need/want 1 RB. Personally I think that should be Don Chaney, but the staff really like Jo'Quavious Marks and a bunch of other guys also. Either way, I don't see how Frank Gore Jr or like Roscoe Parrish III (wr) get themselves a scholarship to Miami.
