$11.5 million over 8 years would be the easy breezy sweet spot for Marner. Taking no less than Nylander, which is obviously important, no ego flex, feels team friendly-ish from a relative cap increase POV, still generational money. If he took that on this round it would feel like you could live with it and still build something around him.
If the negotiations are contentious and the ask/demand creeps into Mackinnon and Matthews territory, with threats to test the market, it probably won’t end up in a good spot.
