We've got 8 owners and are hoping to get four more in our free league. The main difference is that we don't draft team defenses, we draft individual defenders and they are scored on tackles, sacks, INTs, etc. And of course, the normal offense positions too.
This should be a very active league as all of the owners so far are from my past fantasy leagues so I know that they are serious players.
