Statistics/Roster/Scheduling/Etc System for vb4

[HerbToken]

I'm looking to run leagues for online sports video games on my websites, in both teams and singles format. I was wondering if there is any known system that would integrate everything including stats, rosters, schedules, etc in synchronization with vbulletin 4.2.x?

thanks in advance

To clarify, I'm looking for something to manage a league for an online soccer/association football video game.
