NBA Top Shot team competition.

Tom Burwell

Each night, for every active NBA team, the top 5 entries with that team listed on their TS profile as their favorite face off against the top 5 entries of the real-life opposing team.
Moment Ranks could keep track of who made it into the top 5 for their team most often, and of course keep track of which teams are leading in the standings.
This wouldn't really work for the playoffs, but I think it would be a fun incentive to root for other fans of your favorite team throughout the NBA season.
