Kucherov last year, this year and moving forward. Easily.
realistically I think McDavid would outscore Kuch if they switched teams. Not by a ton, mind you.
All those players were on significantly better team than the present Oilers, except for the mid-late 80s Pens, and I believe the 05-06 Pens.
let me put it this way.... put both players on equal teams, McDavid outscores Kucherov.Much like Kucherov is outscoring McDavid.... not by a ton mind you.
