HAS ANYONE DONE THIS?

For those who play on the Miggle boards, being that they are small, has anyone ever tried playing 7 (or 5 man, as well as 9 man) man football? I guess this would be one QB, one Center, two Guards, two WRs, and one RB? One could of course make a WR a TE or whatever. Defense? You get the picture!

The advantages is with less room one now has more space with less players. I know it isn't in keeping with much of the league/tournament play out there,..but it could be a start?
