I’m thinking Kopitar for Hart this year. No way they can deny the NHL’s clearly best, most-responsible centerman who also scored 93 points. He had 70 more PK minutes than the next-best guy in the top ten in scoring!
As a New Jersey fan I'm biased towards Taylor Hall for the Hart. They would have been in the basement without him, and for the first time in his career he really became a key player in big spots.
