I pointed out that Matthews was the best 5v5 goal scorer in the league during his first three NHL seasons, and in those years, he rarely played with Marner. I’m right.
That's not what you said.
First you said that "Matthews led the league in g/60 in both of his first two seasons.". That was wrong.
Then that turned into "Matthews led the league in 5v5 goals per 60 in two of his first three seasons" That was also wrong.
Now you're switching it to "Matthews was the best 5v5 goal scorer in the league during his first three NHL seasons". That one is finally right.
However, the Marner-related conclusions that you're trying to draw from it are still wrong.
Matthews' G/60 has improved since, and his three best G/60 seasons came while playing primarily with Marner.
Marner was an elite 5v5 player prior to joining Matthews, and he produces just as well as Matthews.
Marner's linemate quality isn't much different than his peers, and he earns his points like anybody else.
You attempted to discredit Marner's excellent season by isolating a small sample of 5v5 production stats, but then the bigger sample of those 5v5 production stats showed Marner to be one of the best players in the world since 2018, so now you're scrambling to discredit everything he's ever done by falsely attributing it to somebody else.
