Just like painted art made a transition from realism to impressionistic forms, sports could do the same.  The basic concept here is to add animated features to sports event broadcasts, or even replace the real visuals with a fully simulated alternative.  Imagine football players who look like characters out of Avatar.  Or special effects that show small explosions when a big hit is made.  Or when a player gets injured, the video might show their arm actually being ripped off an blood squirting everywhere.

The video broadcast would have to honor all of the actual stats of the game, but could embellish certain aspects.  If the effects could be applied quickly, then games could be shown almost in real-time.  Otherwise they would be shown with some delay.  

One way to think of this is that the broadcast could be a video-game-like reprsentation of the sport, using the actual play of the players as "controllers."  You might even embed special sensors in the uniforms (and shoes, helmets, etc.) to assist with accurate tracking of movements.
