Nix's mother has what ten kids to feed, or did when he grew up and he stayed because his mother told him too, even though HE would be a first day NFL draft pick, easily.
Personally, I think that Wood needs to have a big game for us to be able to keep AL off-balance and keep Theo fresh throughout the game.
Even then, I don't know if EITHER RB is a first day pickup, anyway. Last ND RB that went in the first round was Bettis, right, so there is a major decision for Cierre to make, that much is certain.
And besides the NFL is only for about 5 years for a RB, if not less. An ND diploma is life-altering and sets you up well for the rest of your life. So, even if NFL does not pan out for him, Cierre can still parlay his diploma into something very worthwhile.
