None of the teams named successors to their fired coaches.

Lions owner William Clay Ford axed the 59-year-old Marinelli one day after Detroit's 21-31 loss to the Green Bay Packers sealed their ignominious place in the record books.

"We didn't succeed on the field in terms of our record," Marinelli told a news conference. "But they succeeded in everything I wanted them to do.

"We came a long way in terms of how to be a football team. The record doesn't show it. But it's a start, it's a foundation."

Detroit replaces the 1976 Tampa Bay Buccaneers, who went 0-14 in their inaugural season, as the NFL's benchmark for futility. 

In three seasons in Detroit, Marinelli posted a 10-38 record and departs having won one just once in his last 24 games.

Crennel, 61, was 24-40 during four seasons with Cleveland. The Browns were 10-6 a year ago but slumped to 4-12 in 2008, ending the season with six straight losses.
