Pretty good online article from GreenvilleOnline.com (I hope this reference is allowed here...if not, please delete):
Interview with Coach Sands: he says he doesn't expect a "RB-by-committee" approach for USC this season, and that Wilds and Davis are front-runners to be the "feature back" for USC. Whoever wins the job will reportedly get 60%+ of the carries.
The two feature somewhat different running styles. At 5-foot-9 and 215 pounds, Davis is considered the shiftier of the two, with the 6-2, 218-pound Wilds described more as a power back.
However, Davis said, Wilds has speed to spare.
“The dude ran a 4.4 (40-yard dash) this winter,” Davis said. “You can’t sleep on Brandon about his speed.”
