25. David Klingler (1992, Pick #6)
If you want to make a pie chart of the reasons why David Klingler ended up being one of the biggest busts in NFL history, you could cut the pie right down the middle, attributing half of it to being a product of the run-and-shoot offense at the University of Houston (and struggling to acclimate to the NFL game as a result), and the other half as simply being drafted by one of the most hapless NFL organizations throughout the 1990’s (the Cincinnati Bengals).
Regardless, after winning a grand total of four games in his first 24 starts over three seasons, the Bengals — who had used the 6th overall pick in the 1992 NFL Draft on Klingler — found themselves with the worst record in the NFL after the 1994 season, and the first pick in the ensuing NFL Draft.
