How many 175 pound, or even quick running backs do you see on sundays or even starting for top 25 programs? Having a rb that can turn a 1-2 yard run to even a 3-4 yard run makes a huge difference on down and distance.
Hell, even when Oregon was putting up numbers that had big running backs like freeman and blount.
Nebraska definitely needs to get some size at rb. I get they are playing wandale at rb because they literally have no one else. You dont win in college football without good/great rbs. Nfl is about the qb and college is about the rb.
The small ones play 3rd down rb in the nfl.
Cook, barkley, fournette, chubb, jones, bell, coleman, drake, McCaffrey, all of them are 210+ excpet McCaffrey and he is the smallest at 205 or so.
