Jason Peters
One of the biggest success stories for the Buffalo Bills in terms of signing undrafted free agents was Jason Peters. The Bills signed Peters as an undrafted free agent in 2004 after he played tight end at the University of Arkansas.
However, almost as soon as he was signed the team began learning the offensive tackle position and after a year on the practice squad ended up starting 10 games in 2005. He became the full-time starter at left tackle in 2006 and spent the next three years there, two of which were Pro Bowl seasons.
In 2009, Jason Peters was looking for a new contract but the Buffalo Bills were hesitant to do so and eventually traded him to the Philadelphia Eagles for a first-round and fourth-round pick as well as a conditional pick the next year.
At the time, this seemed to be a fair trade however the career Peters has had makes him one of those players the Buffalo Bills regret trading away.
He is currently in his 18th year in the NFL and 13th with the Philadephia Eagles. He has become one of the best left tackles in the NFL and likely will end his career in the Hall of Fame. He has made nine Pro Bowls, two times on the first-team All-Pro and six times on the second-team All-Pro.
While the Buffalo Bills have found their long term answer at left tackle in Dion Dawkins, that hasn’t always been the case. If they kept Peters, they would have not had to worry about one of the most positions on the football field for nearly the past 20 years.
