It's not like the voters hate him. He finished 5th in voting in 2013/14 despite being pretty far behind most other forwards in scoring:
Here's a look at the top 10 forwards in Hart voting the year Bergeron finished 5th overall (the ones not listed were goalies Varlamov (4th), Bishop (10th), Rask (11th)):
Place. Player (Voting Points): Games - Goals-Assists-Points
1. Crosby (1340): 80 - 36-68-104
2. Getzlaf (877): 77 - 31-56-87
3. Giroux (435): 82 - 28-58-86
5. Bergeron (137): 80 - 30-32-62
6. Seguin (84): 80 - 37-47-84
7. Pavelski (71): 82 - 41-38-79
8. Kopitar (58): 82 - 29-41-70
9. Toews (53): 76 - 28-40-68
12. Benn (35): 81 - 34-45-79
13. Perry (29): 81 - 43-39-82
He's currently projected to finish with 80 - 32-39-71, and is certainly more important to the Bruins success this year as he has to pick up a lot more slack.
I don't see why he wouldn't at least be nominated. Let's take a look at the other frontrunners:
- Kane is a given.
- Karlsson most likely won't be able to get Ottawa into the playoffs, which should take him out of contention, but we'll see.
- Washington has been firing on all cylinders the entire year, which creates that "who do you choose?" scenario. They have 3 players in the top 11 in scoring (Ovechkin, Backstrom, Kuznetsov). While Holtby earned a ton of credit earlier on, his numbers have faltered down the stretch to the point that he may not even win the Vezina now (Kane's teammate Crawford looks to have the edge in that battle).
- Stars are 11-12-4 in the New Year. In that time, these are the numbers for their two stars:
Benn - 27: 8-11-19, -16
Seguin - 27: 9-9-18, -17
Again, a significant example of "trailing off". Now, the first 30 games are obviously no less important than the last 30, but consistency is what I'm looking at here.
- In the reverse of that example, Crosby and Getzlaf have come on like gangbusters in the second half, but their first half left a lot to be desired.
- If a Shark gets nominated, is it Thornton, Pavelski or Burns? They have a Caps thing going on where it's difficult to choose.
I probably threw more names in there than I had to, but the point stands. Why would Bergeron not at least be nominated this year?
