Programs differ on what they want behind the plate. Some programs like the traditional catcher big strong kid with solid frame. Others are looking for the more athletic kid rangy etc. There is no guarantee that a kid will ever develop the ability to be accurate on his throws. If a kid is already demonstrating that he can throw accurately that is a definite plus. Coaches do look for arm strength at this posistion and feel that it is alot easier to teach proper mechanics than develop arm strength. I would have to agree with that.
