Above average 3C and below average 2C... Solid middle 2C. He's got good all around game and is a good 200' center where you can put him with two wingers and have a shutdown line. Can take D zone face-offs and he's good in those areas. Drowning on the Habs this year where he was doing well in the two years prior.
Not going to force you to like him (if you don't) but those are my reports on him. But if you think you can get a better center in a trade or UFA this summer. I can respect that
I too don't really get what's a "middle 2C". A 2.5C? What?
I've liked him since seeing him in Helsinki in the 2016 WJC, he was noticeable in their team in a good way.
So it's a bit concerning he has visibly looked outright disinterested this season; and that's perhaps a bigger concern than the low production you'd expect in a struggling team.
Lehkonen happens to be a very apt comparison piece here: never takes a shift off, always a gung-ho effort, no matter how the game is going. Dvorak is definitely capable but right now he isn't doing much good for his trade value. I mean if he's on the trading block at all.
(That said, we never really know how much and in what way players are aware of the benefits of tanking for the team's near future... Could be some conflicting messages going around in the subconscious mind... Everyone wants their team to become a winner, after all. Human nature and all that, we aren't immune to it.)
