He's arguably been the best Blues player with the puck tonight. Beaten his man multiple times with the puck on his stick, and created time and space for himself a number of others. Lots of escapability with the puck, both in space and on the line, at ES and with the man advantage. A number of really nice passes, and he's getting the puck to the net...not empty shots that are being gobbled up, either. No panic with the puck, and if he had any bad turnovers, I didn't see them.
It was a meh night defensively, but the whole team kind of stunk when it came to puck support and battles tonight. Dunn's not a player I would expect to dominate on that front, anyway, so maybe I'm grading on a curve there.
Either way, his transition impact and puck poise are extremely advanced for a rookie defenseman. His skill set is going to be a tremendous asset for the Blues.
