Panthers rookie quarterback Cam Newton has impressed his teammates during Carolina's informal workouts this month. Newton worked out with teammates on Wednesday, flew to Washington, D.C. to meet the president in the afternoon and then hopped back on a plane to make sure he attended the final player-organized workout Thursday. "He showed up every day early. He's working hard," Panthers linebacker Jon Beason said. "He's interacted well and he's shown some great leadership." Newton can't talk with Carolina's coaching staff, leaving him to learn the playbook on his own without a contract because of the NFL lockout. "Preparing as a quarterback in the NFL is completely different," he said. "The terminology, the blitz schemes, and at the end of the day, you're not playing freshmen anymore. You're playing grown men. This is where speed comes into play at all times."
