When I think of the top rookie quarterbacks of the pre-Super Bowl era, I think of three guys, each of whom took home a title in their first pro seasons. Hall of Famer Sammy Baugh -- the crown jewel of the 1937 rookie class -- was the NFL's first prolific passer; he was among the top quarterbacks in the NFL in his first year, which he capped off with 335 yards and three touchdowns in the Washington Redskins' 28-21 win over the Bears in the NFL Championship Game. Eight years later, Baugh and Co. were beaten in the title contest by rookie Bob Waterfield and the Cleveland Rams. Waterfield, who had the leadership presence of a veteran, wound up entering the Hall in the Class of 1965 -- the same class as fellow former Cleveland signal-caller Otto Graham. Graham posted a passer rating of 112.1 -- an insanely high figure in those days -- while leading the Browns to an AAFC title in his rookie year of 1946. The Browns were among the three AAFC teams to be assimilated by the NFL for the 1950 season -- joining the Baltimore Colts and San Francisco 49ers -- largely because of the immense success of Graham and his teammates.
