For Winnipeg, it is Scheifele. Buff is up there in my mind, but slightly behind the Jets best (sorry Wheels and Laine) player. He's made more great plays these playoffs than I can recall, he's stepped up physically and he's played a 200-foot game.
You can say most of that for Byfuglien too. With Buff, people see his big hits and personality and that overshadows everybody else. I think the praise for Buff is definitely warranted, and he may still with the Conn Smythe, but right now I'd put Scheife the Knife about half a percentage point ahead of him.
