George Steinbrenner changing managers 19 imes in a 21 year period.
Belichick is closest and he would have to coach until around 74 and average 10 wins a season. Not likely.
IDK if this is a record but I don't see this happening again.
inarguable.1972 Miami Dolphins winning %
1976 Tampa Bay Buccaneers and 2008 Detroit Lions losing %
inarguable.
