Braun has been solidly defensively, anyone thinks he's better than Provorov or Niskanen is crazy, anyone who thinks he's trash is foolish.
He is exactly as advertised, a top flight defensive defenseman who does a lot of subtle things to suppress shots but is pretty much an offensive cipher, especially his weak ass shot, which is worse than Voracek.
Which is why he's a good partner to mentor Sanheim, whose biggest issue is sloppy turnovers and getting himself out of position. There's no question about Sanheim's offensive prowness, he just has to clean up his defensive play. Sanheim can handle the puck and Braun can tell him on ice where to go.
