May be a little smaller but will be faster. Nordstrom isn't short. He's 6'1" 195 lbs. So he theoretically replaces either Backes or Ritchie. I don't see the big loss here.
Lindholm is no hobbit either at 6' 185. Shoot, replace Ritchie and Backes with Nordy and Lindholm and the Bruins are a better team instantly.
