Since 1967, the first year of a combined AFL-NFL draft, the Bills have had the top-overall selection four times. O.J. Simpson (’69) is in the Pro Football Hall of Fame. Bruce Smith (’85), when, or if, he ever retires, will certainly join him in the gridiron shrine. Tom Cousineau (’79) opted to play for the Montreal Alouettes of the CFL, and never stepped foot on a field for Buffalo. His NFL rights were later traded to Cleveland. And then there’s Walt Patulski. The No. 1 pick in 1972.
