Can anyone define 7 on 7 for me?

[Hail Varsity]

I was reading the update on the visits from Keyshawn's players and it references his 7 on 7 team.

My sense has always been that it's a passer and receivers skeleton league where guys switch roles when they're on offense or defense.

I've never seen it played and wondered if anyone can give me more specifics? Who are the 7 guys in the formation? Is there a pass rusher? No tackling? No flags?

Thanks
