Again, I'm not suggesting they have no say, however the GM holds more leverage and is under no obligation to capitulate to a player's demands if it is not in team's best interest
Dubas had given JT $11M to set the new salary structure on the Leafs
He made a last minute deal after allowing WN to hold out, made him whole, and front loaded $10+M
Then he allowed Matthews to beat him for a 5 year deal, at the 2nd highest cap hit, with 93% in signing bonuses.
Followed by giving away a first to dump Marleau's $6M and took on Clarkson so he had $11M in cap ready to go.
By the time Marner negotiated it was too late for Dubas and Ferris just waited until training camp was about to start to get what they wanted.
The best analogy I can think of is trying to play poker with your hole cards showing to the rest of the table.
I don't really have an issue with the JT signing, maybe $1mil rich, but we didn't think the cap was going to stagnate. At the time I was thrilled to have a 1-2 punch with Matthews/JT. Considering how past championship teams had won with a good 1-2 punch of the middle I thought this was a great idea. Definitely hasn't worked that way so far though.
Nylander, I thought was slightly favoured for him, maybe $500k high. Would have been nice if Lou signed him in the last year of his deal, but I don't think Nylander wanted to sign before the end of that season anyways. I could care less about the front loaded $10mil, and I doubt anyone else does as it is MLSE's money. His contract is good value now.
Matthews the number is OK (not amazing by any means), term was too short, but a longer term doesn't help with cap space this season. He was the only one I was worried about being offer-sheeted, and I was happy they got him done before the end of the season, and I can live with the number given.
Marner, again, $1.5-$2mil too high IMO. So I don't see how anything changes with Marner, minus trading him in the end. He wanted close to Matthews, and Matthews wanted around McDavid money and more than Eichel. Maybe Matthews wouldn't have been offer-sheeted so we could have hardballed, I personally didn't want the Leafs to take that chance at least.
