Teams changed and adapted to make themselves better, instead of standing pat. There is no need to micro analyze if our situation is EXACTLY the same... no two teams situations are ever EXACTLY the same. I mean, Tampa changed 5 of 6 D, and somehow that is only changing their "depth defenseman?"
In the end, they are comparables of teams that changed directions, by whatever means necessary, and went from out of the playoffs, to winning the Cup. It happens, and no, the details are never EXACTLY the same.
