I have had enough of this core.
As a fan, move Matthews and Marner are you getting equal players back? Probably not. Are you getting a 'package' back for those 2 that helps the team? Maybe, maybe not.
But, I'm ready for something different. If you move them and this team gets less total regular season points next year, so what, the year will be more interesting. If you move them and the package you get back makes the team BETTER next year, that is what fans want.
But keeping them? The entire regular season means nothing again, isn't intereting again, and each year that goes by the entire hockey season watching the Leafs in the regular season just gets less and less interesting and fun.
Ready for major changes to the core, whether that ends up being for better or worse next year.
