A year ago, Ron Edwards was brought to Carolina to make an instant impact at the defensive tackle position.
Almost instantly, he ended up on injured reserve. Edwards tore his right triceps during his first training camp practice.
The aspirations for Edwards haven't changed as he enters his second season with the Panthers. The 6-foot-3, 315-pound tackle will again be counted on to play a big role along the defensive line.
Additionally, Terrell McClain and Sione Fua will look to further prove themselves after injury-shortened rookie campaigns as the Panthers work toward interior line stability.
