If the coach places the best defender (in the definition of the verb defend) of the team next to him, there is a reason.
Slafkovsky will always be underestimated because he doesn't score a lot of points. But yes, he is better than Nick Suzuki. All Montreal fans will tell you that. If Montreal had to make the No. 1 pick again, management would take the same player. This is an extremely rare profile. Whereas a Nemec... you can have the same type of player more easily. Levshunov for example.
I know I would have a different opinion if I didn't watch all of Montreal's games... but even yesterday, with a 2-point game, Nemec didn't make as strong an impression on me as Slafkovsky usually does.
Points are really very deceptive in hockey.
There are plenty of players that I underrate because of the points and the fact that I only watch them 2-3 times a year (especially Western Conference players). I am more aware of this than ever because I know that in Montreal, there is a big gap between the statistics and the overall level of play. Guhle is the same. Fewer points than Matheson but better.
By the same way, Siegenthaler is also very undervalued by points.
