We did this ^ in our league, worked out okay. If you lose atleast you had a 50-50 chance to get your team.
But I like call them first!
As far as LB's idea it definitely adds a deeper level, but I don't know if it'd be fair to guys who may not be as good, and are playing just to play with their home city/state team, and just want to atleast be competitive. NC rep over here.
