44 basketball teams play a game. How can the competition system ensure fairness and reduce the number of games? Thank you! The first two rounds can be eliminated! ! !

Using the elimination system at first, or always using the elimination system, will reduce the number of games, but the wonderful games will be reduced. Suggestion:

The first stage is divided into 1 1 groups. After the draw, there will be two rounds of elimination, 33 games, and 1 1 team will qualify.

The second stage is divided into four groups, round robin, with the first point qualifying, *** 10, and four teams qualifying (only one in one group).

The third stage decisive battle, ***4 games, how to play does not explain.
