As it turned out, it might have been a blessing for Perriman that a hamstring injury precluded him from working out at the combine in Indianapolis. Now, his only 40-yard dash showing for NFL scouts is the Wednesday clocking they won't soon forget. So while scouts might choose to rely more heavily on the slower times from Indianapolis by prospects who made vast improvements on their pro days, they won't have any such slower time to fall back on with Perriman.
