If the Texans lose OLB Mario Williams, USC's Nick Perry could be a viable replacement. Like Williams, Perry (6-3, 271) is an athletic freak who displayed his potential on Monday, running unofficial times of 4.50 and 4.56 in the 40 to go along with a 1.57 time in the 10-yard split. Perry, who led the Pac-12 in sacks last season, has the potential to be moved to OLB in a 3-4 scheme similar to what the Texans run.
