The Panthers exceeded every expectation with their offense last season, so they want to make sure to keep the entire depth chart intact.
Webb hasn’t thrown a pass in two years with the Panthers, but they wanted to keep him because he’s versatile. He’s also a big part of their special teams, and can plug in as a receiver as needed, something few other quarterbacks can do.
They’ve made sure to insulate themselves at quarterback. Last September, they extended backup Derek Anderson’s deal, making sure they have a reliable Plan B (and now Plan C) behind league MVP Cam Newton.
