I think only the top 4 teams playoff for the championship and everyone else goes into consolation brackets. And it's not 2 teams from West and 2 from East. Even though I'm 2nd place in the west I wouldn't have made the championship bracket if it started today. The 3rd place team in the east has more points than me.
6 teams. Each division winner gets a bye week. Playoffs start Tomorrow (Or today if you live on the east coast and UK)
