I'll be honest I don't think I'd trade Podkolzin for Holloway back right now if given the choice.
No offense to Holloway, he'll be a decent player I think too, but I think once Podkolzin gets more comfortable and learns to read how to get some easier looks off Draisaitl or McDavid, he's going to be a enormous pain in the ass to play against.
Dude is maybe legit one of the strongest players I've seen in the NHL, Trouba tried to push him back and the guy barely moved an inch, he murdered Nashville's enforcer in a fight. On the forecheck he just goes through players. I see nothing wrong with his shot mechanics, it's just a confidence issue.
Surprised by some of the good passes he makes too, like he's not McDavid or Drai out there or anything like that, but there are so many players on this team that just make mind boggling decisions with the puck and he just makes good straight forward plays. Set up Draisaitl for a heck of a one timer last game.
