Also, the strength of schedule is just another variable for people to complain about. I like the idea in theory, but I don't like the idea of having a potentially subjective variable determining playoff seeding or whatever.
I understand why certain people are upset. They play in a very difficult region and get left out of the playoffs, while other teams play in a weak region and get to benefit from that region. To that I say, that's a life lesson. It seems like the same people who are upset about everyone getting in are also upset about weak scheduling, and teams from weaker regions. That is a juicy contradiction to me. You yell, "What about the integrity of the game", "What kind of lesson are we teaching our children", when all teams get in the playoffs. But turn around and yell, "It's not fair", "Our region is hard", when the top 1-4 get in.
Each situation is a life lesson, life's not fair, better luck next time.
