You shouldn't need a Flyers skill comp to tell you if he has a heavy or effective shot. Can you even remember a time the guy has taken a slap shot? He even admits he never takes them. Having a heavy slap shot and then never taking a slap shot, but labeling the guy as having a heavy shot? It'd be like describing a knuckle ball pitcher who had a fastball clocked at 103, but never throws a fastball, as a flame-thrower.
The only shot JVR takes is a wrist shot, and if it had any sort of heat, accuracy, or release he'd be scoring at a ridiculous pace, because with his skating, size, and reach, he almost routinely gets clear off-wing shots...
