Default Re: Quarterback Ball Velocity at NFL Combine 2008-2014

If a thrower tries to "over" throw their velocity typically drops. Sports performance is all about manipulating tense to create force. One of the things you'll find with elite athletes, it's not just how much tension they can produce in working muscles it's also how quite the antagonistic muscles are as well. Effectively everything is working in concert. If you try to over throw then the muscles that are supposed to be shut off and up being tensed as well creating an opposing force thus reducing the total output.

For example, using completely arbitrary numbers, if a thrower stays relaxed and loose when throwing, his tricep may fire at an 8 while the tension in his bicep drops to a 1. If the same guy over throws, his tricep may fire at a 8.5 but his bicep is now at a 2.5-3 so the net result is indeed lower. This can happen all along the kinetic chain as well
