It still matters alot because these camps could injure them at the last minute. The Cowboys sent a guy up here once who’d been injured during a Speed camp. ( I get a number that are sent up here for repairs after these camps)
He was 6ft 1in and 335lbs and had run 4.7 in the 40y. They had him run another and he pulled his hamstring.
He blamed himself but I think they should have stopped him after he scored such an exceptional run for his size on the first try.
The natural instinct is to get carried away after knowing your time and really try to put one out of the park, which is never going to lead to anything good!!
