What does it matter they "backdoored" into the game? That implies they didn't deserve to be there, which is poppycock. We played a team that "backdoored" into the game, and got clobbered (what does that say about us?). If we would have won the game, would the title not count because we played a team that "backdoored" into the game? Of course it would still count. They were the best team in their division that followed the rules, so they deserved to be there more than any other team in their division.
It's not like they were handed the trophy. They earned it by winning the championship game.
