I have a kind of similar question about this game: (1037867)
As my opponent had only 4 players, why did his coach think it was a good idea to bench some of them during the game?
And should'nt my team have done better? ;)
The game engine generates players supposedly to represent fans out of the crowd. If you do the match replay and click on the box score, you will see that one of them was actually the high scorer for Jena.
But maybe the game wasn't supposed to be played. If you do the match replay there is no shot chart. And there is some sort of glitch displaying the player names for the team with 4 players (they're overwritten).
It might be that the game engine isn't programmed to take advantage of a totally inept player. If you were playing man-to-man defense, one of your players could be over getting some water, while you played 4 on 4.
