Jerry Rice didn't run a good 40

Jerry Rice who stands out as the best WR of all time ran a 40 in the 4.6 range and was dinged due to the slow time.

Since Van didn't run a 40 all we have is the Zebra tracking at the Senior Bowl which says he plays fast on the field.

I bet if they had the Zebra tracking back in Jerry Rice's day we would see some fast times.
