I think 3x3 would make sense for both sides. I know everyone in this thread is saying oh Maroon should go cash in big on the open market, but do people seriously think that some team is going to pay Maroon 5-6M for 5-6 years? Maroon would be lucky to get over 3-4 years of the open market given his skating ability and age, and don't think the entire league doesn't know that he is essentially the grunt and opportunist on McDavid's line. He's absolutely a valuable player to the Oilers much more than he would be to any other team.
At least with a 3x3 deal he keeps his scoring up and has the potential to get another contract when he's 33. If he signs elsewhere for say 4-4.5M x3-4 years I would not be surprised if he's out of the league after that contract.
So he should accept 9 million and stay with he Oilers, out of the goodness of his heart, instead of taking 16 million with someone else?
Would you? Knowing that every player is one nasty hit from being done?
