Out of curiousity I have gone back and listed the # of owners each franchise has had (along with their overall W-L record for all 8 past seasons).
Denver - 1 owner - 110-18 (.859%)
San Diego - 4 owners - 76-52 (.594)
Kansas City - 5 owners - 40-88 (.313%)
Oakland - 2 owners - 29 - (.227%)
New England - 1 owner - 103-25 (.805%)
Miami - 4 owners - 87-41 (.680%)
New Jersey - 4 owners - 73-55 (.570%)
Buffalo - 3 owners - 51-77 (.398%)
Pittsburgh - 1 owner - 73-55 (.570%)
Cleveland - 3 owners - 61-67 (.477%)
Cincinnati - 6 owners - 47-81 (.367%)
Baltimore - 5 owners - 47-81 (.367%)
Indianapolis - 1 owner - 63-65 (.492%)
Jacksonville - 5 owners - 57-71 (.445%)
Houston - 6 owners - 44-84 (.344%)
Tennessee - 5 owners - 42-86 (.328%)
An interesting thing to note are that franchises whose owners have remained from the get-go have the best record (in each division), and in some cases an advantage that many other owners may feel is insurmountable. However the thing that I am most curious about is how the AFC South does not have a single team with a .500 or better record over 8 full years.
