A co-worker of mine had a really cool idea for a heads up tournament league. 32 teams follow the NFL season with players registering and getting a team. Your matchups would follow the sports schedule for the 16 week regular season with all players facing off one day of the week. I'm looking for info on Heads-up play, bracket creation, tournament software, structures, or anyone who has run these regularly or is well informed about headsup tournament play.
