Random tangent:
I helped coach our HS team for 7 years in the early 2000s. A couple years after I quit coaching, one of my co-workers had a son on the team. One day we were talking football and he wondered why we didn't throw more quick slants. I told him our QB - who I had coached as a freshman - would simply not hit his three step drop and throw the ball. He always double-clutched or something. I would even tell him in practice "when you hit that third step, throw the ball. I don't care if he's open. I don't care if he's looking. Hit your third step and throw." But I still couldn't get him to do it.
At the game that Friday night, we were down inside the 10 yard line and they called a quick slant. The QB double-clutched the throw and - because that gave the defense time to react before he threw it - it ended up getting picked off. I walked by my co-worker and just shrugged.
