The Cleveland Browns are on the cusp of becoming the second team in NFL history to lose 16 games in a season.
The Detroit Lions were the first to do it, back in 2008. And by virtue of point differential (the Lions were outscored by 249 points during their winless season), Detroit is considered the worst team in NFL history.
Which got us to wondering, what are the worst teams across the other three major sports?
Here's a look:
MLB: 2003 Detroit Tigers
Manager: Alan Trammell
Record: 43-119
Season summary: Yes, the 1962 Mets went 40-120, but that was an expansion team.
