Well guess what? Scouts.com has one of his "needs improvement" as ARM STRENGTH. Go figure.
It's all relative really, most all high school QBs need to improve their arm strength before heading into major college football. Couple that with the fact that Star has only been playing the position a few years and the fact that he's a superb athlete and I don't really think arm strength will be that much of a problem for him in another year or so. JMHO.
