Dan Fouts
This Hall of Famer played his entire career with the San Diego Chargers (1973 to 1987). Fouts was one of the most prolific passing QBs of the 1970s and 1980s, however the Chargers were not able to reach the Super Bowl in his 15 year stint. He led the NFL in passing yards four straight years, and was the first player in history to ever throw for 4,000 yards in three consecutive seasons.
Drew Bledsoe
During the 1990s, Drew Bledsoe was considered the face of the Patriots franchise, he was their first overall pick in 1993 NFL Draft. Under his tenure as starting QB, the Patriots ended an embarrassing eight-season postseason drought, qualified for the playoffs six times, and even made one Super Bowl appearance. He was named to the 1995 Pro Bowl and was the youngest quarterback to appear in the NFL’s all-star game at the time (all in his second season with them).
