My complete speculation on why JR quit:
1. I do think the ownership was meddling to a degree that JR didn't like. I don't think that means "I want to trade Letang and they won't let me", but I do think they had their hands in somewhat and JR didn't like it.
2. I think the bigger reason was that being a GM during a pandemic just sucks. He doesn't travel with the team, so he can't meet face to face with players. With how much roster turnover that has happened in the last year, I can easily see how that would drag down JR's morale. He has even admitted that the last 11 months has been really challenging for him.
JR may claim he's not quitting because of the pandemic, but I think it's more likely that it's something small that's finally pushed him over the edge but he was pushed up to that edge by the pandemic.
I just listened to Steigy on NHL radio. Not a bad listen when he's not peddling the kool aid line. I think since going off TV he's been in a communications related role with the team, so I took what he said as kind of the 'here's what people who work for the team but weren't in the room are kind of guessing':
1. Said two things in all the interviews yesterday stood out to him:
(a) Morehouse saying he wasn't surprised suggests there were some issues
(b) Allvin emphasizing how he and Sully were on the same page
From that he opined that JR wanted to do something that ownership wouldn't allow. He didn't know what or if it was because they were saying NO per se or because ownership wanted to be involved in the process (he alluded to Morehouse's 'Allvin has Mario' comment, to suggest maybe those above JR were a little more involved lately than he preferred).
NOTE: Not Steigy's comment, but it's entirely plausible IMO that the involvement per se, rather than a hard NO on some move, would be enough to give JR the perception that ownership's faith in him had diminished. Not saying it was correct to feel that way, but it certainly could explain why the trigger came now instead of a month ago as well as the 'hard no on something' theory does.
2. He then noted when you consider JR's age and being isolated in Carolina, maybe the unique COVID situation and his contract being up in June just made him say it's time. I think there was a curiosity on Steigy's part if this would've happened if JR was in Pittsburgh and things were running normally.
3. Asked about JR's legacy, Steigy called him the fixer who completed the puzzle. Someone from the outside who took a fresh look at what had been assembled. He said JR completed the puzzle for Shero in the same way Patrick did for Esposito and EJ and Shero did for Patrick.
4. This led to the who next question. Steigy said they'd look at everything but he hoped for someone with an outside perspective. The only name he floated was Ron Hextall. Specifically noted as part of his pitch that the Pens are soft but also acknowledged that Hextall's undoing in Philly was that he was too patient (Steigy didn't mention it, but I suppose the counter to that is Hextall AGM to Lombardi in building that Kings cup team and perhaps he learned from experience to find a better balance given his time in Philly).
All in all, it reminded me of listening to Pierre McGuire on TSN radio. There's the television character completely worthy of ridicule, but the radio version actually is pretty articulate and insightful.
EDIT:
@DesertPenguin . . . I saw your post on Tallon. Didn't realize they didn't hire him, but the attempt certainly feeds into the 'more involvement from above' thing Steigy was talking about.
