I usually like to ease the reader into a topic before I start throwing numbers at them. This time, I’ll switch that up and lead off with a player comparison. The following table compares the first four years of the two Super Bowl-winning quarterbacks who made the fastest career starts in the salary cap era.
After his first four years in the league, quarterback B, leads quarterback A in every category (league MVP, first team All Pro, Pro Bowl, AP Offensive Player of the Year, passing yards per game started, yards per attempt, touchdowns, interceptions), except for perhaps the most important one, Super Bowl wins.
