That's a fair statement, usually the playmakers are the ones who have better chances of scoring more goals simply by default, considering there are two players that can register an assist as opposed to only one goal scorer, thus giving you more chances to score points.
It's a fairly simplistic, but logical explanation and I'd agree that Eichel is the better playmaker of the two. However, with that said, I think Matthews gets a bad rap because everyone sees 40 goals and 20 something assists for his first season and thinks that he's Ovechkin who does nothing but shoot.
I think too many people don't watch Matthews enough. I've had center ice every year since it's inception and access to out of market games before that and it's hard to consistently watch another team on a regular basis, especially with that other team being in your time zone and playing the overwhelming majority of their games at the same time. I have had a hard enough time following Vegas, Toronto and the few other teams that I try to follow on a regular basis, being that I have total ADHD when it comes to watching hockey on center ice. So, when some random person tells me that they specifically watch another team that's not in their market on a regular basis, I have a hard enough time believing them as is, nevermind when they're spewing nonsense like the other poster was.
