There's no way anyone in their right mind would make that trade. As much as I like Barzal, I wouldn't trade Podkolzin one for one.
This is a big strong kid who plays with grit, will stand up for teammates, plays a 200 foot game, who's a great passer, and as Miller has said, has the hardest shot on the team.
Like you said, this is a player we will win cups with.
