Speed is important but

Yes we all want to throw as hard as we possibly can but you have to remember that throwing say 85 on the corner and doing it with comfort is better than throwing 91 over the plate throwing as hard as you can and not being comfortable

Very true I’d rather hit corner than throw juice down the middle. If you get a good hitter that speed will mean very little and if you throw him down the middle your just asking for a rip.
