Drew Bledsoe
The notion of ever seeing Drew Bledsoe in another uniform seemed distant in the mid-90s when the quarterback was leading the Patriots to new heights, including a Super Bowl appearance in 1997. But the emergence of Tom Brady when Bledsoe went down in 2001 to a serious injury ultimately made Bledsoe expendable, and he was traded to the Buffalo Bills on draft day in 2002 for a first-round pick in 2003.
