Not at all.
Bruins don't have marner, heck, they have less talent than the Leafs and yet they ruffle marner's hair each time they meet.
Leafs could lose a marner trade, but make the team better. Maybe they aren't the one of the highest scoring teams.
A reallocation of marner money is the goal, perhaps Tavares money would be better and a new coach that insulates marner, so he gets less attention.
I'm not sold on marner nor Tavares being moved.
Would not be surprised with "new coach will be given the opportunity" to better utilize the talent.
