I always hate these polls where you are not supposed to take the contract in the discussion. Fine, we might as well talk about them in the point when they are coming into the league. At that point, it's Matthews. However, when you consider that Matthews will probably get a huge contract compared to Barkov (and rightfully so), then it's again, a different discussion.
I don't really want to answer, they are both elite #1 centers. Matthews is better offensively, Barkov better defensively. Take your pick.
