Would be good to break up some of the betting into events.
Events:
March Madness 2014
March Madness 2015
Groups:
Bets With Mark, Steve, Mike
This way each event will be a zero sum game. Events would have a start and end date, groups will be long running. The Events and groups can be either public or private. Public events and groups show up in players history, private ones don't unless you have access to the private groups too when viewing profiles.
