1 year UFA with a NMC isn't getting what you're hoping buddy.
The most comparable trade is probably Tkachuk to Florida, made by the same GM with limited options. Say what you want about huberdeau now, but he was elite at the time.
Other trades to look at are meier, lindholm, PLD, giroux, etc.. it obviously depends on what people claim he's worth, but people thinking Marner has little value are beyond delusional, the guy is a top 3, at most top 5 RW in the game and is elite both ways.
We don't need to trade him, and he doesn't need to accept a trade either, but there would definitely be a lot of interest.
