It's Pionk for me, although it was very close with Howden and Hajek.
The big thing is that I'm not sure that Hajek or Howden's upside (as a #2 D or C to me) is that much higher than Pionk and Pionk is already in the NHL and is more of a sure thing.
A couple things that sell me on Pionk's upside:
- He scored 0.5 ppg in the NHL this year. That's comparable to Dougie Hamilton, OEL, Werenski, Ekblad, etc. It's a small sample, but he scored almost a PPG in the college too and he makes some really high end plays that show off a lot of skill, so I think there is cause to believe in his offensive potential:
On Letang:
I couldn't find the video, but the play where he flipped the puck to himself and rushed through the entire caps team to create a scoring chance stood out too
- I thought he looked solid defensively against the other team's top forwards. In particular, he stopped Ovechkin several times in that Caps game.
- He did well on the US WC team that won Bronze against top NHL players.
In a nutshell, I think Pionk might have more offensive upside than Hajek and still has the potential to be a sound defenseman against high-caliber NHL players, plus he is already in the NHL and has less development / adjustment risk than Hajek.
I would add Rykov. I think he should be in the discussion the Hajek / Howden for the next spot on the poll and would certainly vote for him over Lindgren, who is already included in the poll.
