Marleau is a marginal player on this great Leafs team. Johnson and Hyman are about on par with Marleau now and Lindholm/Gauthier are grittier. It wouldn't be the worst thing in the world if we could simply just trade away his salary.
Marleau would have to agree to that though, so it may not be possible.
My suggestion is just something we could do it trading him wasn't an option.
(There's obviously still a trade involved but Marleau wouldn't leave Toronto)
