Our league is set up with a 60 man roster during the off-season that has to be trimmed to 48 by the NFL's cut down day.
You have an 8 man inactive squad which consists of 5 IR guys and 3 practice squad guys (must be rookies, or someone who has never been on an active roster before).
There is trading all year long, even during the playoffs.
We do our dynasty rookie draft the week after the NFL draft is over.
It's really great to get a league started like that, but it takes a lot of time so I would suggest making it a money league because you want the same people back year after year and in a free league, people could just bail at the drop of a hat.
