Of course he knows how to take a slapper, but in general, when he does, it comes off at pretty low power (compared to most NHL offensive dmen). Being a real threat with your point shot is all about being able to consistently get off a very hard, fairly accurate slapper - Rielly isn't there yet. This is definitely something he can work on with time, but you look at the slappers from the top offensive dmen in the league (Karlsson, Subban, Chara, Weber, Doughty, OEL, Phaneuf, Letang, Mike Green, etc.), they have WAY better shots. Rielly's slapper right now is Kaberle-esque, improving on this will be key towards Rielly developing into a better offensive dman, and being a guy you really want out there on the PP.
