I've mentioned this in two other threads now, but this one is probably where it should have gone in the first place.
Against the Jets, he made a play that very few D men could make. He and Little were racing for the puck in the corner (D zone). Larsson wedged his way between Little and the boards, picked up the puck at which point he was hit by a second player. In the scrum he ends up with one hand on his stick, but still retains possession on the puck with two guys draped over him. He stickhandled with one hand, maintained possession, then made a break out pass with still just one hand on his stick. No other D man on the team could have made that play had they tried it 100 times in practice.
Those are the things that get me so excited about his future. He makes rookie mistakes, and they're to be expected, but you see things from him that an 18 year old should not be able to do. Things that are all but impossible to teach. His future is very bright.
