To answer your ? / speak to the bolded.
It says / tells me Marner has not produced as many points in games 4-7 as the others full stop. The fact (or excuse) he is viewed by some as a passer and not a shooter doesn't hold water here - if he's the top notch playmaker he should have racked up points via assists in games 5 - 7 shouldn't he? Are we going to say others not scoring is the problem because Marner's playmaking was at the same level in the playoffs it was in the regular season?
I get that this can easily be a chicken and egg thing, "guys don't score so the playmaker looks bad" vs "playmaker doesn't set up the guys to score well in the playoffs so they don't score and look bad" - the truth is it's probably both to some degree but when the elite playmaker has half the points of the next player from the 'core'.....
To me it doesn't make sense to say Marner shouldn't' be expected to score because he's an elite playmaker and not a shooter, IMO he should be both at 10.9M but in games 5-7 he hasn't really been either.
It's fine to say the entire team has failed in games 5-7 for the most part and you wont' get any argument from me but I think it's fair and accurate to say Marner has failed harder than the others. He has 5 points in the past 5 years in games 5-7 which is half of any of the other core players 7 plays on PP1 and the 1st line vs JT or Willy who are on PP1 but 2nd line.
As far as your stats around "series clinching" games most series are going 5 or more so to me the stats around games 5-7 are far more important / telling.
Honestly I don't care if a guy isn't great in game 4 but can pick it up in games 5-7, series sweeps don't happen often enough IMO.

Honestly I care that a player is great throughout the playoffs - and we have yet to see that from _any_ of them. But I firmly believe that games 1-4 matter too. Playing like garbage and then trying to come back and win it in games 5-7 is some serious Ricky Steamboat action. We don't need that, either.
The reason I like looking at whether a game was clinching or not is that not all game 5s are created equal. Games 6 & 7 are, by definition, a game where a team can be eliminated.
To the point I think you're making, though, when it comes to rising to the occasion - which is that "in the moment" thing Marner has definitely left was wanting more, but unfortunately so have our other core players. But Marner has tragically bad games 6&7 stats.
Now I'm looking at their careers as a Leaf, not just from 2019, but:

In Game 7, if it's not Nylander, the team sucks. What is really telling about the team is that in games 5-7 the power play goes to poop. If you use that same metric (that you'd want to dismiss, but I think it's a crucial metric for a player and a team) of clinching games:
The Leafs are 24/123 on the PP in normal games (19.5%), and 4/43 (9.3%) in series clinching games. Our opposition, for the record is 33/124 (26.6%) and 10/43 (23.3%) in those same games.
Those stats can't be laid solely at the feet of Marner as much as many want to do so.
For the record I've said all along that I'm not opposed to moving on from Marner or Nylander - as long as the trade brings in a piece we need. Cap flexibility with no clear plan on what to do with the cap room is pointless and makes us worse. But both are excellent players who have been maligned unfairly at times for much of their time here.
