Leafs are on their 4th GM since the Reilly draft pick. "Since then leafs have rebuilt properly...." is a bit of an overstatement as Burkie and Nonis were trying to win now but both crashed big time.
Shannahan executed a pretty fantastic franchise rebuild... They still haven't taken it to a cup win, but after a decade of being as bad/worse as we've been the last 4-5 years, the leafs have been a top-tier/contending team for last 2-3 years and look poised to remain in that upper-echelon club for at least another 3-4 years if not more.
He, like Yzerman in Tampa, executed a pretty textbook rebuild that started from embracing a long-term lens and moving tactically and strategically toward that vision without sacrificing short-term concerns for long-term goal.
one can easily point to missteps here and there, but when viewed as a whole, both of those leaders managed to take what they learnt in being part of the Red Wings dynasty and incorporate the key elements into their franchise overhauls, successfully so.
Sad thing is that Yzerman is now well underway to doing the same thing in Detroit... should the divisions re-set as they were, we'll have 3 franchises in direct competition that are building the right way, plus Boston that, for all of Neely's issues, is pretty damn good at keeping excellence clearly in their focus.
We desperately need leadership overhaul if we want to avoid this 5 year run of mediocrity turning into another decade of ineptness
