Classy doesn't win Cups. Name a team that won on "class" in the post-Gretzky era. None. Not one. All had an element of grit/toughness that could be quantified by a single player/line that played every game. The Wings didn't have that this season and haven't had that since Dallas Drake.
The 1997 and 1998 Wings were both very tough and gritty teams. They could go toe to toe physically with any team in the league every game. That was an overall team toughness that hasn't been seen since on the Wings. It disappeared with the losses of Lapointe, Vladdy, Ward, and Kocur. These guys played minutes every game, and 2 of them were more than just big bodies and fists. In 2002 the Wings won the Cup with pure skill, but there was still a Grind Line. A line that could go out when you were down one and crash and bang and piss the other team off. That didn't exist this season. And hasn't since Downey was dropped.
The 2008 Wings were not supposed to win the Cup. They were not as skilled as the Pens offensively and didn't match up physically. The Wings overall grit was better as their more physical players could actually contribute more than PIT's grinders. Plus, Dats and Z were physical and kept Crosby and Malkin in check every shift. Pavel and Z were both hurt this year and were not physical at all vs. BOS. That's bad news when they are supposed to be the shut down line. Kronwall can't be physical either, if he goes out of his way to level a guy it isn't Lidstrom picking up the slack, it's Brendan Smith.
Grit, size, goaltending, and balanced lines win Cups in this era. Need at least 3 of those to make it to the Finals. Wings had half of one. Boston has 4.
