If Cross was indeed injured, like the coaches said when the season ended, 5.3 yards per carry and 10 TDs is mighty impressive. I think he's earned more carries.
The only issue I have about that stat, is its deceiving. Not trying to start a huge debate or argue with you The Dude, but 5 of those 10 TD's came out of conference play, while 0 were gained at UCLA. In conference play, he had 53 carries for 247 yards @ 4.6 ypc. 31 of those carries and 132 yards were against Purdue and Illinois where we had a heyday on the ground.
I am not trying to down the kid at all, just saying I personally have not seen enough to say "he needs more carries". IMO, he needs to prove he can be a quality back when we need him, not just against weaker opponents with really bad rush defenses.
