You missed the point.
In general you're coming off as a complete troll with your exaggerated misuse of not-remotely-advanced stats to push contrarians viewpoints.
If you just want to stick to stats, here's a second-year undergraduate concept that is more advanced than anything the so called advanced stats people use: The Bayesian Information Criterion. Colloquially translated it means that if you're looking at a hundred different stats you're bound to find one that supports your viewpoint, and you keep doing that. Another translation is that you can support any argument by applying a completely irrelevant model with a million parameters. In many of your posts you refer to untold numbers of stats, many of which you don't explain how they're defined, which means they have no value.
It's not like I'm digging in the bottom of the barrel to find obscure, cherry picked stats to prove a point, I'm looking at pretty basic ones, like Goals and Expected Goals (both for and against). If a player is on the ice for a lot of Goals For (GF), they're probably doing something right. If a player is on the ice for a lot of Goals Against (GA), they're probably doing something wrong. Same goes for Expected Goals (xG). From there, you'd want to adjust for context, so you can look at something like RAPM. The simplistic explanation of RAPM is that it takes a metric (like GF) and "isolates" it to a player's individual impact, taking things like teammates, competition, usage, zone starts, team strength, etc. into account (ie contextual factors). The full write-up on it is
here if you're curious. Feel free to ask about any other stats or terms I've used that you feel I haven't explained adequately enough, or ones you don't understand.
Circling back to your "points", no, Byron is not better than Joe Pavelski. You'll notice Pavelski just had 19 points in 27 playoff games, and he's always been a playoff warrior. That is something that is common among high-talent players that aren't necessarily regular season warriors - they can raise their scoring in the playoffs. Meanwhile Byron cannot. You'll notice that Phil Danault said that playing with Byron and Lehkonen was a nightmare situation offensively.
I think Pavelski's playoff production this year had a little bit more to do with him nearly doubling his on-ice shooting percentage (7.27% in the regular season 13.13% in the playoffs), though that's not to say that he isn't a good player (or even that he's someone who elevates their game in the playoffs). I think he was a little unlucky in the regular season, shooting percentage wise. I also don't think Byron is a better player than Joe Pavelski, I just wanted to point out that Joe "top 6 forward" Pavelski and Paul "4th liner" Byron produced at similar rates at 5v5 over the last 3 years, so maybe people are underrating Byron (who, by the way, had back to back 20 goal seasons in 16/17 and 17/18, and was on pace for 22 goals in 18/19 before the injury). In my opinion, a reliable 20 goal scorer (despite not getting PP time) is a valuable asset to a team's top 6, especially when said team has issues with scoring goals. That's all I'm trying to say. Not that Paul Byron is better than Joe Pavelski, but that people are underrating the guy that scores at a higher rate than Joe Pavelski.
As for Danault calling playing with Byron and Lehkonen a "nightmare situation", I don't think that's really accurate. He expressed disinterest in playing in a "shutdown" role, which it appears the 3rd line would be, a shutdown line. I think it has a lot more to do with the usage of the line than the wingers sucking offensively.
Which brings us to your Danault worship. No, the Habs are not better served by have ng Danault as a 1st line center. There's the obvious issue that he can't play on the power play, and the Habs were awful there this year. Trying to win games 2-1 is also completely useless when being behind 2-1 or 3-1 in the third period. But the actual issue is that it screws up the lineup, and having Danault on the third lineup contributes to the rest of the lineup playing badly, as it screws up the structure of the team. Having Suzuki on the first line would yield two separate improvements to the team: Suzuki would be a better 1st like center than Danault, and Danault would be a better third line center than Suzuki. Suzuki, like Pavelski, also has better playoff potential than Danault.
While I won't try and pretend that Danault is some secret PP god, him "not being able to play on the PP" isn't really accurate imo. The only forward on the Habs with a higher primary assist rate on the powerplay over the last 2 seasons is Jonathan Drouin. I think the coaching staff feels that they're better served by having Danault save his energy for tough 5v5 matchups and PK time, so they don't play him on the PP. If he got regular PP time I'm sure he'd put up the point totals people expect out of a #1C, because he puts up #1C caliber point totals at 5v5 (he was 9th among Cs in 5v5 points this year).
A player playing on the first line is doing so at 5v5 (that's where lines 1/2/3/4 are deployed. So a "first line" player doesn't necessarily have to play on the powerplay, as long as they're playing up to snuff at 5v5. Danault not being a PP option doesn't mean he sucks at 5v5 (in fact, he's great at 5v5).
Nick Suzuki played with a variety of linemates this season, but was mainly playing with players who many would consider to be "top 6 forwards". When he was on the ice, the Habs scored 1.91 GF/60 at 5v5, and got 43.42% of the goals, or had a GF% of 43.42. When Phillip Danault was on the ice, the Habs scored 3.59 GF/60 and had a GF% of 60.21. If you're concerned about trying to win games 2-1 when you're behind 2-1 or 3-1, then Danault is a much better option for the 1C spot than Suzuki. Danault produced at 5v5 this year, Suzuki didn't. Danault was the stellar two-way C this year, Suzuki was the defense only C. The Habs top line was one of the best lines in the league this year, in part thanks to Danault's contributions. Having him play on the top line is not an issue, or else the line wouldn't be putting up a near 60 GF% with them on the ice.
