18. 1995-96 Vancouver Grizzlies
An awful team to bear, this is the first of three Grizzlies squads on this list, culled from just a four-year span. While the 1995-96 Grizzlies amassed more wins than the other two iterations, they set a record by losing 23 contests from February to April, a mark that wouldn’t be broken for 15 seasons.
