The Cleveland Browns
It’s easy to forget that New England wasn’t Belichick’s first head coaching job. He cut his teeth in Cleveland after Art Modell hired him in 1991. Belichick built a big reputation for himself as a defensive coordinator in New York and became a hot property. But Cleveland was a volatile environment for any young coach.
He did bring them a playoff win in 1994 while he made the bold decision to cut QB Bernie Kosar. However, Modell wanted to move the franchise to Maryland. He fired Belichick after their final season in Ohio before they went to Baltimore. There was no love lost between them after Modell fired him on Valentine’s Day in 1996 (via NBC News).
