Yea ok, we all know this. Maybe what he’s trying to say is that there whould be some kind of exacting standard, or something. I might agree with him. But at the same time coaches know the difference between grass and a track or at least they should. yea but its definantly possible to run say a 10.5x and then run a 4.3-4, cause that what alot of those guys run in the 100m or faster. But theres times when a guy can put up a fast hundred but he’s got slow ecceleration hench a slow 40 time.
