Panthers rookie quarterback Cam Newton has been working out with former NFL signal-callers at the IMG Academy in Bradenton, FL. Chris Weinke and Ken Dorsey have been working with the first overall pick in last month's NFL Draft. Dorsey played for current Panthers offensive coordinator Rob Chudzinski at the University of Miami. Thus, Dorsey knows most of Carolina;s new offensive system. "It's a lot of material that I do not know, but each day I'm going in and learning something," Newton told the Associated Press. "So by the time ... the lockout is lifted and I get a chance to talk to Chudzinski and (QB coach Mike) Shula and meet back up with the team, I'll be on top of my game."
