IMHO 1-2 million always matters, but in Marner's case maybe it doesn't matter much because if you're paying him 11/12/13/14 (or god forbid the rumoured ask of 15.5), he's just not worth it at any of those numbers.
If you're happy with just making the playoffs, then sure, keeping Marner makes sense, that's not me though and I'm pretty sure it's not most fans. f*** compiling assists in November, help the team win in the playoffs. He's too much of a whiny baby to do that though, his meltdown last night I would think made that crystal clear for anyone who hadn't figured it out yet.
Do you really want this loser back? And are even willing to bend over again on contract negotiations because 1-2 million more doesn't matter? SMH.
