Justin Zwick was watching a lot of movies at his parents' house in Ohio, close to giving up his dream. "I'm thinking I've got to start earning some money some time, and I can't live off my parents forever," the former Ohio State quarterback said Monday. "Then all of sudden you get a call." The Panthers wanted to give Zwick a shot to keep his football career alive. Zwick, who had stayed in shape since leaving college, first worked out for the team Thursday and the Panthers signed him over the weekend. He practiced at an optional workout Monday.
