Michael Hayes (Houston), an undrafted free agent RB, will likely receive plenty of opportunities to impress because of the departure of RB Mike Tolbert (Panthers). Hayes' athleticism is showcased in a college highlight video, especially his ability to stay on his feet after initial contact. But Hayes said he was overlooked in the draft because the Houston Mustangs play in Conference USA. “If I was in our offense in a big conference, I honestly think I would have been drafted,” Hayes said.
