Via the NHL:
Letang, 26, shared the League scoring lead among defensemen with 38 points, taking seven fewer games to reach the total than Subban. Letang missed 13 games with an injury.
Exhibiting a fluid skating stride that allows Letang to eat up ground and get back on defense, the Penguins defenseman topped all defenseman with 33 assists, a total topped by only 11 forwards this season.
Only six defensemen averaged more time on ice per game than the 25:38 Letang played per game. He played for Pittsburgh coach Dan Bylsma on both the penalty kill and the power play, where he had 13 of his 38 points.
He probably won't win but, if he does, get ready for a bunch of "Erik Karlsson would have won but Letang's teammate injured him!" posts and articles from Ottawa.
Only one Penguins player has ever won the Norris Trophy. Current Maple Leafs coach Randy Carlyle did so back in 1980-81.
