They made the playoffs in an asterisk year. Under Dubas, people would dismiss that season.
My entire point is that you are saying he would do better if he inherited the current team - it's a flawed premise based on his transaction history. He would bring the same problems that he's always struggled with (contracts, drafting, etc.), just with bigger repercussions. It'd essentially be a Jim Benning situation where you have Beagle, Sutter, Roussell, Eriksson, etc. signed to inflated contracts in the bottom six, but your depth would be twice as bad because Burke cannot draft for squat so there are no ELC's to supplement your core.
Dubas also did not inherit the core on ELC's. He inherited the core coming off of ELC's. Lou inherited that situation, and left the next regime in handcuffs with the Zaitsev/Marleau deals.
It always comes down to "expectation". Yes, expectations are sky high, but go look at polls before the playoffs. Both last off-season and pre-playoffs the majority of this board voted that they supported Dubas' moves (adding toughness, leadership, etc.). Now it's revisionist history all over again. Your problem is actually with an underperforming core. Dubas hasn't even been here as long as Burke.
