I completely disagree.
I think he's the most underrated player in the NHL. He plays on a team that is perennially one of the worst in the league with some of the worst talent, yet he averages right around 1PPG, which is incredibly good. McDavid's the best player in the NHL, I don't think Matthews, Eichel, any of these players are going to be as good, but I have no clue how this perception has formed that Matthews is another tier from Eichel, I believe it to be incredibly naive, and purely based on the Toronto vs. Buffalo market and one playing for an up and coming team, the other playing for a rotten team. I actually think Eichel's better, and I think that'll be proven out over their full careers.
Eichel on a team with some talent could be the second best forward in the NHL eventually. He really has 0 help, he's playing on a line with Evander Kane and Jason Pominville, which is my point. I wouldn't be surprised if Dahlin joins him next season, thats how bad Buffalo is. Eichel's the most talented American born forward that the USA has produced, he has a crazy power stride with speed, really high level passing, a very good shot, and good hockey IQ. He just needs some help, he's going to be one of the NHL's best hockey players, but a kid that just turned 21 having to completely drag a really bad team by himself isn't easy. McDavid can't even do that with Edmonton right now, and he's a better player than Eichel. Edmonton is also better than Buffalo.
"Coach killer", I don't care. Lebron James is a coach killer, midseason he fired the coach, appointed the coach he wanted, and coached the team himself with his friend posing as coach. They won a title. When you have elite players in a team sport, they have the right to fire the coach. I'd condone any of the NHL's elite players firing their coach, if they didn't get along with them. Its their organization, everything needs to revolve around them.
