Trotz didn't luck into a Cup. But he also didn't singe-handedly deliver one, though he behaved after the fact as if he had.
It was a team effort. The guys in the front office, the guys behind the bench, and the guys on the ice all pulled together to make that happen. Because that's what it takes.
And all the critiques of GMBM regularly ignore how Trotz f***ed him over after the Cup run. He had a contract, a raise, and roster ready to repeat. And he threw it all back in their faces because his ego was bruised. And look what happened... neither he nor the organization was able to make another successful run absent the collective dynamic that they had built together.
