Last year the RB position was by committee, like several other positions. Warren and Porter started the year going essentially 50/50, although Warren got the majority of receptions out of the backfield and Porter did more pass pro. However, Warren got more than half of his seasons total yardage vs. SJSU and eventually lost carries to Carter. By KSU Carter was getting as many carries as Porter and Warren, but Carter was in trouble with the coaches for much of the season for mistakes, practice issues, and who knows what, so he didn't get the playing time his production called for. By Baylor, Young emerged as the top performer and by Kansas he was the primary RB.
2017 RB stats:
Daniel Young - 373 yards, 4.6 ypc, 3 TD. 153 receiving yards, 1TD
Chris Warren - 314 yards, 4.4 ypc, 6 TD. 229 receiving yards, 2 TD
Kyle Porter - 261 yards, 3.1 ypc, 4 TD. 43 receiving yards, 1 TD
Toneil Carter - 252 yards, 4.8 ypc, 3 TD. 31 receiving yards, 1 TD.
This year the starting spot is once again for grabs. Young and Carter underperformed in the Spring Game, and Porter is still Porter.
I'll update this post weekly during the season with stats.
