We're coming off an Olympic year and if you were like me, you were glued to the TV during all sports, especially the track and field sprints. Remember Usain Bolt's insane speed during the 100 meter dash? Amazing, especially for a dude that stands 6'5".
Clearly, Bolt would beat out Otis Merrill in a 40 yard dash, but I think Merrill could keep in there with the speed he exhibited in this clip below (which doesn't show him running until about halfway through):
Unofficially, Otis Merrill ran the 40 yard in the 4.42-4.45 second range. I love to see these guys sprinting...even better when it's on Lambeau Field for a touchdown!
