I hated that reference to baseball no longer existing by the 23rd century because supposedly people don't like to play competitive sports anymore. The HELL? Get rid of that crap on the double. Indeed, go whole hog in the other direction. Show a state-of-the-art future ballpark, with room for hundreds of thousands of fans. And who knows how many teams exist in Trek's time? There could be hundreds of them. And an 'Interplanetary World Series' to boot. (The Cubs probably still haven't won...)
I agree with this, which is why I decided that one of the OCs I created was a basketball player while in high school. Even three- or four-hundred years from now, people will still act like people. I'd love to see a Quadrant (?) Series featuring the Pike City Pioneers (Cestus III) and the Ki Baratan Cloaks (Romulus)--the latter of which advanced to the series after sweeping the Cubs, who were forced to play their home games at Pavel Chekov Field (currently US Cellular Field) because Wrigley Field finally crumbled to the ground.
