The injury part is one of my main concerns along with the bad mechanics that it produces. I know some of it relates but most does not from a full running throw to the mound. I think it also produces disappointment for many kids when they say they throw 88 and when they get on the mound and only throw 78. I can't imagine any high school coach caring and even fewer college coaches except it does show what can be reached but only after they start allowing pitchers to run and throw.
