Washington Huskies receiver John Ross beat Chris Johnson's record 40 yard dash time with a 4.22. It's not yet official.
Johnson's record time is 4.24.
Ross absolutley flew, making it look effortless. But it took all his body has as he was seen stretching out his legs after the potentially record setting sprint.
Hopefully he didn't hurt himself. I think it's safe to say speed like that can only increase his draft value.
