BEREA, Ohio — The NFL's rookies are learning that hard knocks aren't reserved for the field.

This week, the league's newest players are taking a crash course in all that goes into being a professional athlete at the Rookie Symposium. The players are taking part in panel discussions on a variety of topics, including health and safety, non-discrimination, domestic and family life and drug awareness. The league invited several former and current players to share their stories of success and failure.

On Monday, Cincinnati cornerback Adam "Pacman" Jones spoke to the players about his off-field struggles. Jones recently pleaded not guilty to a misdemeanor assault charge and has had other issues that led to suspensions.

San Diego linebacker Manti Te'o said the lesson he learned from Jones' speech "was to never give up."

The players took a break on Tuesday and instructed some area kids in football drills.
