Ryan Leaf was the number 2 overall draft in the 1998 NFL Draft and is considered one of the greatest NFL Draft busts of all time. Leaf had a Wonderlic Test Score of 27 which considering the trajectory of his NFL Career seems rather high in retrospect. Leaf will always be compared to the player drafted before him, Peyton Manning, who went on to play 18 years in the NFL and is arguably the greatest quarterback in NFL History. In recent years, Leaf has served time in prison for drug related issues.
