The Cleveland Browns, with their disastrous 2016 campaign, stand out as one of the worst NFL teams of all time.
The Baltimore Colts experienced their greatest low during the early 1980s, with records for most points allowed and fewest punt returns.
The Tampa Bay Buccaneers struggled in their inaugural season in 1976, going 0-14 and suffering numerous injuries.
The 2017 Cleveland Browns became only the second team in NFL history to go 0-16, with rookie QB DeShone Kizer struggling.
Coaching decisions, player performances, and injuries played a significant role in the failures of these teams.
