A basketball court isnt 150 metres long.
The ball is a different shape, too. And there are a few other fundamental differences.
But... I think it makes sense that AFL footy borrows tactics from other sports. There are sports that have been around longer (though not too many), but certainly sports that are played by more people, have more money spent on them, more coaching and analysis done than AFL, so I think it's reasonable that some sports are more fully evolved than out game.
Our game is pretty chaotic, not least because it's played on a MASSIVE surface with a shedload of players and bugger-all rules about where you can go. However the precision plays of American football, the ball movement of basketball and the structures of soccer are all things that I think have been/will continue to be borrowed and re-purposed for AFL. One could argue the bench rotations now look an awful lot like ice hockey "shifts", and subbing out players is almost like relieving pitchers in baseball. You have your main guy, and a closer.
