I'll go ahead and recommend you check out my games over at XEG Studios. All free.

Football
Basketball
Hockey
Full disclosure: GM Games are MUCH BETTER. I can't hold a candle to what these guys do, but maybe it will scratch your itch.
All can be heavily customized, but lack any semblance of depth like what you see here. All games are single-game, though I'm working on implementing season mode for Basketball. If successful, I'll carry it over to the other games.
