Ok first off let me say I got this from MFN 8 ( https://mfn8.myfootballnow.com/forums/thread/1/529?page=1#977 ) and ( https://mfn8.myfootballnow.com/forums/thread/1/528?page=1#978 ) so I thought I would do it for this league and I cant sleep so I figured why not do it now??

anyway I have gone thru each team , listed each number of owners for each team and I have also added their wins - losses record for the 15 years .
Btw Ties were counted as losses to make this easier.

here are my findings

NFC East
Philadelphia - 7 owners - 169-71 (.704)
New York - 8 owners - 137-103 (.571)
Dallas - 5 owners - 108 - 132 (.450)
Washington - 10 owners - 102 - 138 (.425)

NFC North
Green Bay - 7 owners - 135-105 (.563)
Chicago - 8 owners - 127-113 (.529)
Minnesota - 8 owners - 105-135 (.438)
Detroit - 10 owners - 71-169 (.296)

NFC South
Carolina - 1 owner - 179-61 (.746)
Atlanta - 8 owners - 113-127 (.471)
New Orleans - 10 owners - 107-133 (.446)
Tampa Bay - 9 owners - 91-149 (.379)

NFC West
Arizona - 6 owners - 137-103 (.571)
Seattle - 3 owners - 128-112 (.533)
Los Angeles - 9 owners - 103-137 (.429)
San Francisco - 6 owners - 79-161 (.329)

Total owners 115 total wins 1891 total losses 1949 total winning percentage .492

few notes
3 divisions have 2 teams with a winning percentage of .500 or higher
Only NFC South has only 1 team above the winning percentage of .500.
also it seems like really Philadelphia and Carolina the top of the class for winning percentage.
it also seems Philadelphia lives a charmed life knowing they have had 7 owners and they winning percentage is in the 700 hundreds.
Detroit , New Orleans and Washington have had the most owners with 10
Carolina has had the fewest owners with 1
NFC North has at least 7 owners and up for all 4 teams which seems like there is a lot of turnover there.
