I want Patrick Peterson so bad it's not even funny. You give him even decent safety help on his side of the field and he will erase one side of the field. Everything about him is near perfect - backpedal, break out of pedal, tracking the ball, tackling, body control, awareness. He is NEVER flat-footed as a habit, something that guys like Mike Jenkins still need to be coached out of.
Patrick Peterson is going to be like a seasoned Charles Woodson, Nnamdi Asomugha, Terence Newman, or Darrelle Revis from day 1. Top tier CB who can play the ball and is physical, and is a coach's dream.
Not only that, he'll immediately push Jenkins to work harder because his job will be threatened, and we'll be insured against Newman as he continues to get older...though until he actually shows some sign of deterioration (ANY sign - just not there yet), I'm not worried about him.
