Knowing I just did the NFC ( https://mfn1.myfootballnow.com/forums/thread/1/967?page=1&x=W7KPZIoK2h#5471) I will now do the AFC.

here are my findings
AFC East
New Jersey - 1 owner - 178-62 (.742)
Miami - 2 owners - 159 - 81 (.663)
New England - 6 owners - 117-123 (.448)
Buffalo - 7 owners - 94-146 (.392)

AFC North
Pittsburgh - 2 owners - 177-63 (.738)
Cincinnati - 10 owners - 103-137 (.429)
Baltimore - 12 owners - 95-145 (.396)
Cleveland - 3 owners - 65-175 (.271)

AFC South
Houston - 1 owner - 136-104 (.567)
Indianapolis - 7 owners - 129-111 (.538)
Jacksonville - 6 owners - 112-128 (.467)
Tennessee - 11 owners - 96-144 (.400)

AFC West
San Diego - 3 owners - 159-81 (.663)
Kansas City - 3 owners - 118-122 (.492)
Oakland - 2 owners - 105-135 (.438)
Denver - 1 owner - 100-140 (.417)

Total owners 77 total wins 1853 total losses 1897 total winning percentage .494

few notes
Only 2 divisions have 2 teams above the winning percentage of .500
Only the AFC North and AFC West have 1 team above the winning percentage of .500
It seems like New Jersey and Pittsburgh are top of the class for AFC in winning percentage
it seems like Miami and San Diego are carbon copies of each other with same winning percentage
Baltimore has the most owners with 12
Denver , Houston and New Jersey have the fewest owners with 1
it seems like the AFC west has the fewest turnover with owners.
