Although we'll never know--these are very interesting points. I mean, we've often discussed these types of scenarios, such as--"what if Mario Lemieux walked into a team that had Kurri, Messier, Anderson, Coffey, Lowe and Fuhr, etc.?" and "Gretzky was surrounded by players like Rob Brown for the first half of his career?" These are entertaining to consider but I guess we need to go by what happened.
That said, in one of the videos I shared, Clarke was discussing his "leadership" and he gave all the credit to Snider, Allen and Shero for giving him the authority to make decisions and "lead", which validates your main point quite a bit. Sometimes I think these are "perfect storm" scenarios. Clarke was perfect for Philadelphia and the Flyers were perfect for Clarke. I don't think Dionne had the same attitude, work ethic and grimy personality that the expansion Flyers needed at the time. Philly is such a blue collar, hardhat and lunch pail city--especially in the mid-70's--that the Bullies resonated with them. Dionne reminds me more (personality-wise) as Rick MacLeish. Flyers fans adored MacLeish, like the rest of the Bullies, but Clarke was our guy. Personally, I don't think Dionne would have turned the Flyers into a Cup team, although the Flyers would have been competitive--like the French Connection Buffalo Sabres.
As for the Kings perspective--that's a good question--I'm not sure what Clarke would have been able to do in a dumpster fire environment.
The Clarke-led Flyers were very much a built from scratch outfit, so there was no existing team ethos (good or bad), no baggage. Keith Allen and Fred Shero, fully supported by ownership, is just one helluva hockey architectural firm.
The same can be said about the Potvin-led Islanders just a few years later. Torrey and Arbour got to build that club from the ground up, no history to live up to or work within (or around).
This is way off topic, but when Dionne joined the Wings out of the powerhouse St. Catharines junior club in 1971, Gordie Howe had just retired. Coincidentally, Montreal drafted Guy Lafleur just one spot ahead of Dionne that same year, and Jean Beliveau had just retired.
We know that Beliveau worked with Lafleur, mentored him, and played a significant role in Guy’s slow and steady transition from a junior scoring sensation to an iconic Hab. Bowman, too, was crucial here in teaching Lafleur how to play without the puck and to improve his defensive game and overall situational awareness.
The Red Wings made retired Gordie Howe the vice-president of Sweet F.A. and buried him in a tiny office in the basement of the Olympia. He was not even permitted to view practices, let alone actively mentor youngsters. Perhaps Howe could have been to Dionne what Beliveau was to Lafleur, but we are talking about the Harkness darkness period in Red Wings’ history, and the Big Guy was getting the mushroom treatment.
Anyway, some clubs (and even lone individuals) are just better than others when it comes to expertly guiding extraordinarily talented youngsters along what is often a non-linear development path. Glen Sather, for instance, has a superb track record in this regard.
This doesn’t change the obvious truth several posters have pointed out — we can only deal with what actually happened, not what ifs.
Still, if people are going to compare Clarke’s otherworldly leadership to Dionne’s rather suspect leadership, recognizing their diametrically opposed environmental venues is useful. How heavily one chooses to weigh these environmental differences is an open question.
