The more I watch Roloson, the more evident it becomes that he's a dirty player. He just drew a penalty by skating into an opposing player and causing a "goalie interference" penalty. Worse, from the reverse view, you can see Roloson pushing off the opposing player with his glove hand making it look like the opposing player bumped him.
Incidentally this was outside the crease, the opposing player was far enough outside the crease that Roloson had to exit the crease to draw this penalty.
That, combined with the constant hooking and body contact, shows Roloson to be a dirty "Slapshot" player.
