Rich Eisen & his combine "talking head" buddy had a video of 2 players running side by side with only minimal difference is 40 times & it resulted in about 3 feet of separation.
Yep. This is what many people don’t get. Those tenths and hundredths matter, big time. It looks minuscule, but side by side, it could make or break a play.
That said, I do also believe that there is game speed some of these guys possess…quickness, in and out of breaks and turns quicker, fast decision making, guys that run better with full gear on than others, etc., so that all has to be assessed also.
