Speaking of offer sheets, if Mitch Marner is tendered a legit offer, what if the Leafs just let it ride and took the four first rounders? Some of the click bait rumuors I've read hint at just such a situation. Including their own picks, that's 8 first round picks in four years. I know Toronto isn't really rebuilding, but first round picks are still a valuable commodity. Just some food for hockey thought.
So with Kadri getting traded to the Avs and Barrie coming back in return the Leafs free up some salary and can afford to match the offer sheet that anyone might toss out there unless it is absurd. If another team offered to sign him to a 10+ mil contract though I'd let the other team have him and take the picks. There is no questions that Marner is an above average player, but I don't know that he is going to we worth that cash AND you have two other guys tying up 22.6 million. Do you really want to have 3 guys taking up 40% of you cap space? The answer is no.
4 1st rounders is just printing money at this point, I'd take it in a heart beat. Even if you don't need the players to stock your team they have value when some other team decides to scrap its playoff ambitions and rebuild as trade bait. The Wild immediately come to mind and with the expansion draft happening in a few years that's also bait to convince Seattle not to take someone off of the Toronto roster. I read today, though I can't remember where, that Montreal's offer to Aho has considerable front loaded bonus money. I can't wait to see what that poison pill is and would be interested to see if any other wealthy team tries the same tactic in the future.
As a Caps fan, I'm concerned about the portents your thread title portends.
The first sign of worry was when they signed Richard Panik for 4 years ;) I think the plan you get the Panik out now and worry about what happens next year when we have to re-sign Holtby and Backstrom. I'm certain the Caps can't afford to sign both at what is going to be a market value that is significantly higher than what they make now. I expect they lose one or both. If they keep both of them expect that someone else gets traded to clear salary.
