Ok, is this too simple for some of you in teaching IF's and OF's how to throw? We teach an IF should throw using a half circle and an OF should use a full circle. We teach elbows should be on a line with the shoulder and to finish up on the other side of your opposite leg to make sure you follow through and don't use only arm (especially for OF's). We have players hold the ball 11:00, 1:00, 6:00 (four seam fastball). Do any of you add a lot more than this? Also, how often do you have a kid who has messed up mechanics, but you leave him alone, because that is what works best for him considering his muscle memory is almost frozen?
