Linebacker Derrick Thomas wasn't just a great pass-rusher for the Kansas City Chiefs. He changed the franchise's losing culture. The Chiefs drafted Thomas with the fourth overall pick of the 1989 draft, and in his rookie year they had just their third winning season in the previous 16. In his second season, 1990, the Chiefs began a run of seven playoff appearances in eight years, the most successful stretch in franchise history.
Why Thomas is best draft pick in Chiefs history: Thomas piled up some impressive numbers in his 11 seasons with the Chiefs before his untimely death in 2000.
