It is a team sport, that's why it makes no sense to evaluate players based on how their team does. Rantanen has been fantastic in the playoffs, Marner has not. Are you really going to argue that's not the case?
If we offered to trade Marner for Rantanen, do you think COL accepts?
If COL offered us Rantanen for Marner, would you accept if it was your decision?
I personally am not "blaming" Marner for anything. I hoping against hope that the reason he hasn't been great in the playoffs the last few years is that he has been given too much ice time, that that will be fixed and this year he kills it for us. I'm not sure that's a valid excuse for his play but I'm hoping.
TBH I don't put too much stock into those fancy stats over small sample sizes. A lot of what you say has merit though, hopefully Marner breaks out in the playoffs this season and everyone will be happy.
Let's be honest here, until Marner produces in the playoffs, many people will be unhappy with him and the offer sheet threats and a few other things have hurt his reputation. That's just the way it is so no need for people to be so upset about it and make these threads toxic. Not saying that's you, I like your posts a lot and I appreciate being able to discuss things in a respectful fashion with people who don't agree with me. That's the fun and rewarding part of being here and that's how every now and then I learn something.
Since I respect your opinion (even if we don't always agree

), let me ask you this hypothetical question:
If you were offered a trade of Marner for Rantanen today, what would your reaction be? Easy decision? Tough decision? Would you need to think about it for some time or do know what your answer is?
