Would be pretty much impossible considering the amount of owners that have owned teams and eventually let them go back or sold them. I'm sure someone could put something together but it would be grossly inaccurate.
Teams change hands so much, support would have to be able to find when each owner had the team and split the w/l total. That would be alot of impossible work
All my team's have had a combined winnin % of 98% wins over 6 team's in 18 seasons. Not counting pre-season, scrimmages, post season, or any game I did not put an effort into winning.
