Only two NBA teams play in one year's championship game.
Two. One from the Eastern Conference and one from the Western Conference.
There really are none. The conferences that hold championship games are those that have so many teams that they are broken into two divisions. The winner of each division will play in the championship game to crown a conference champion. Conferences that are not broken into two divisions do not have a championship game.
Many too many to count.
About 13 or 14 weeks. Not counting the post-season bowl games which span about six weeks, each NCAA football team plays 12 games and has 1 bye week within the season. Teams with the best rankings in their division may play in a conference championship game, and the bowl games will include a National Championship Game now operated under the BCS (Bowl Championship System).
a lot of teams. In fact, about 100!
2 teams from the championship League go up to the Premier League at the end of the season. Their places in the Championship League go to 3 teams from the Premier League.
