I mean, who wouldn't use McCaffrey? If you had McCaffrey on your team you'd be riding him all the way to the New York state championship and beyond. 55 touches a game.
But to pivot off that, if I were in Turner's place, that would be all the more reason to find that one player who could legitimately be all those three backs you mentioned above in one guy. A guy that doesn't come off the field, equally good between the hedges as he is out of the backfield.
Dare I let loose my admiration for Cam Akers, but ... I do like his game. I would easily call him a 3 down back.
Personally I think he's going to be an even better pro than what he was at FSU. Just having a legit line in front of him, that alone, will uptick the bulk production. He's already great at yards after contact, love his spin moves, admire his balance and jump cuts. An excellent prospect, but you put downfield blocking from TEs and WRs, a la Art Monk 20/30 yards downfield on a DB, then you've got homeruns from Green Akers.
Per Love/Thompson, I think they'll role with just one of those two, not both, whoever is healthiest. They're somewhat redundant.
