well usually you set the league on default which includes the categories:
FG% FT% 3PTM POINTS REBOUNDS ASSISTS STEALS BLOCKS TURNOVERS.
alot of people play head to head but rotiss is also alot of fun. head to head is when your team plays a different team each week...then the top 4-6 teams (depending on your league size) play the final few weeks of the nba season in a playoff format.
rotiss is accumulation of points. the team with the most points wins.
i have played both and both are fun...it just depends on the majority i guess.
