I've worked with a lot of real heavy hitters, and Quentin is maybe heads and shoulders, at least a forehead, above just about anybody I've ever worked with. ↗
But I still serve pretty big and that's one of my biggest weapons, so if my shoulder holds up and I can count on it, I can win a few matches and then you never know how the other guys are going to react to the fatigue and the length of the matches. ↗
