A rushed rebuild is one that creates a half-assed core group and then tries to take shortcuts that lead to them not reaching contender status. We have the best young core in the league and are already contenders. We rushed nothing.
Yep, if you have a good elite core, what is happening to the Leafs is what you expect.
Penguins shot up the standings, as did Washington, as did Chicago, as did LA...Tampa had a few hiccups where they were in and out of the playoffs but they too can be counted here.
Bad rebuilds: Edmonton (traded anything of value for one year of success), Buffalo (still stuck), Dallas (they alternate between good and bad years and have no depth), Colorado (see Dallas).
Leafs have much of their core locked up for the foreseeable future and the crazy thing? We still have not seen the best of Matthews, Marner, Nylander, Johnsson, Kapanen, Rielly and guys like Moore, Sandin, Liljegren are still waiting for their turn.
