They don't care of winning in the playoffs, because they only get paid for the regular season. Once the money ends so does the motivation with the results.

I think MLSE and Leafs new CEO has realized this and change is coming to Toronto. IMO
PS. Easier said then done when players have NMC, but where there is a will there is a way.
