again, please understand that Im not saying having a big arm is not good if it complements the qbs good traits
its just not a prerequisite. a pitcher who can throw a FB over 90 mph is nice, but he doesnt have to have plus velocity on his FB to be a good pitcher
he might not ever be a more than a good pitcher, but a mediocre FB doesnt stop him from being at least good.
good mechanics, not tebow like release, and general accuracy ARE prereqs. hence tim tebow will never be a successful NFL qb even if he had the arm of jawalrus
