As training camps begin next season contact the team. They will tell you how to become a walk on and when try outs are held. You will not be with any regular players until you have passed a series of tests. You better be good and be in the best shape of your life. Very few players make it as a walk on. James Harrison of the Steelers got cut 4 or 5 times before making the team. He became NFL defensive player of the year and first team all pro. He is still with the Steelers as a starter and will probably be all pro again. Good luck.
