Pro Football Hall of Fame coach Bill Parcells had a list of criteria when he drafted a quarterback.
Among them: The quarterback had to complete 60 percent of his throws.
Parcells judged on productivity, not on arm strength or mechanics. He wanted a quarterback who started and won a lot of games, who completed a high percentage of passes and who took care of the ball. In short, he wanted a guy who had shown he could play, not shown he had potential.
Parcells' belief system takes on added meaning as the 2018 NFL draft approaches and the Cleveland Browns try to judge between Sam Darnold, Josh Allen, Baker Mayfield and Josh Rosen for the first overall pick.
