Well, Dvorak is playing very good hockey for quite some time now. He's pretty good now. Not 4M good, but 2M x 2 years good. 7th C with the most PK time in the NHL, yet he's 28th for goals allowed (that's f***in great). Meanwhile, his expected goal for % is third C material, and on the upper hand. He benefits from playing with Gally and Anderson, but it's a two-way truth, they benefits from playing with him.
I don't know if he can keep this pace, but he's actually accelerating. Both Gally and Anderson signed for 2 more years, I'd probably offer a 2 years deal at 2M ich and call if a great safety net.
