Chuck Smith: 58.5
Atlanta Falcons (8 years, 123 games)
Make no mistake, Chuck Smith was an impact player who was an All-Pro in 1997 and was a big-time contributor on the Falcons' Super Bowl XXXIII team. His athleticism and technical skill were without question top-tier. Still, to be the franchise leader in sacks with just 58.5 pales in comparison to some of his contemporaries, like Bruce Smith, Kevin Green, Derrick Thomas and Reggie White.
