I think you're getting caught up in either some recency bias or the media hype around his last few months...
Marner had some respectable Selke vote totals last year, in the Bergeron Selke domination era. To be in the top 3 finalists goes beyond a few Homer votes. He was 10th in 20-21, 16th in 21-22 Selke voting. Most years he finishes well ahead of Matthews in voting (which probably dilutes his vote totals with splits). That doesn't just disappear - Marner needs out of the media fishbowl and pressure cooker Toronto sports are. That shit doesn't come out of nowhere and it doesn't just vanish, it's far more likely that Marner had a bad year
Additionally, he played limited shifts on DEFENCE in the NHL without getting caved in this year (link below image)... Yes, it's against the Coyotes and a major Leafs roster composition flaw pre TDL - but it is also noteworthy they chose Marner to slot into the blue line, rather than a 4th liner.
Marner had his hissy fit in the spotlight with his glove throwing tantrum that saw spotlights in the media circuit - Tarasenko also had his moments here, but we're not a media darling (remember his spats with Hitchcock?). Our shenanigans seldomly hit the highlight reel, even during our prime with the exception of the Sanford Bortuzzo fight in the cup year.
I think the only portion of your post we can agree about is that Marner is going to want more on his next deal than we'd like to pay him to stay with us. He's a very talented player and he's been highly paid before, he's going to be asking for a raise and I don't think salary wise he's a good fit... But to suggest that he's a poor defensive player and thus a bad fit here is wrong.
He's also near a PPG in playoff point production which is also something that gets ignored when discussing the Leafs failures in the post season - Marner produces, but their line-up has lacked depth due to major roster construction flaws...
I think wherever Marner ends up if he's the one moved is going to be VERY VERY HAPPY about their acquisition.

Mitch Marner did his best Shohei Ohtani impression on Thursday when he took shifts as a defenceman in the Toronto Maple Leafs' 4-2 win over the Arizona Coyotes.
