Well that is very convenient
This is essentially the potential fallout we have been hearing about recently of Murray blocking a buyout claiming, he is not healthy now so as per CBA you can't buy out and injured player.
Murray now guaranteed he gets his full ridiculous $8 mil salary, whereas a buyout at 2/3rds rate would have costed him over $2 mil in lost wages.
So Leafs are playing the game, if you're injured now preventing a buyout then you're also going on LTIR to start the year, and not going to be healthy in a few months to start the season.
Once on LTIR, "Don't call us we'll call you"
