Well a pitcher does require a lot of body parts working in motion in order to throw 95 miles an hour with pinpoint control. If one piece isn't working, it can mess up everything else. same goes for a quarterback, but they play hurt. They also get pulverized by 280 lb. monsters every Sunday. QBs throw 90 miles an hour? I bet they could come close when throwing a baseball. Just because throwing a football wouldn't register 90mph doesn't mean they aren't throwing with the same explosiveness a pitcher does. Man, I don't know. Most pitchers throw with so much effort on each pitch. I just don't see the same with QBs (except maybe Favre a few times a game). But the differences aren't really close. QBs get hit, yes, but they're playing once a week for 16-20 weeks. And they throw what, 25 passes on average (really a guess)? And yes, they throw warm-ups, but they aren't nearly the same velocity. Pitchers throw 90+ pitches every 5 days for 6 months and that doesn't include warm-up pitches every inning. That's, what, 150+ pitches every 5 days, plus bullpend sessions in the middle. Though not every pitch is 90 mph, the 90 mph fastball isn't even the worst pitch for the arm. And if a QB is hurting, he might be less effective. But the precision required to get ML hitters out is much higher than the precision required to throw a pass that can be caught by a WR everywhere from his toes to 10' off the ground.
