MLS Lineup Database
Here it is, finally. I put a lot of work into this. There are 16 files, one for each team, plus overall stats and notes. It contains the results, lineups, and goalscorers for every official game that every MLS team has played in. Plus, stats on the total number of appearances (sorted into starts/subs) and goals for each player. And there's the overall records for each team. Just a ton of info that any hardcore MLS fan needs. Check it out.
EDIT: This is Version 1.1 (12/02/05), which fixes a couple of mistakes.
EDIT2: A couple more small things have been fixed (3/27/06).
EDIT3: Uploaded it again due to another small mistake, see comments. I've been doing that every time I notice something wrong (4/17/06).
