I met Adrian Peterson at the weigh-ins on the first day. He was coming off a spectacular collegiate career -- placing second in the Heisman race as a true freshman and running for 4,245 yards in three seasons at Oklahoma. I remember thinking as I stood next to him that he was a bit taller than I expected. His noticeably upright posture was a result of his muscular physique -- extremely lean with massive biceps. His entire body seemed as if it had been sculpted for the cover of DC Comics. I reminded myself to not be impressed. Quite honestly, I wasn't a fan because I recognized him for what he was -- my competition -- and I had to prove my worth.
