Multiple scouts and GMs tell CBS Sports' Clark Judge that Patrick Peterson will likely end up at safety "in three to four years."We've noticed in Peterson's games that he struggles in space, particularly when playing "off" receivers. He's far from a true shutdown corner when giving any kind of cushion. At 219 pounds, Peterson will immediately be the heaviest corner in the league. This isn't to say Peterson will be an ineffective player; he could be plenty dominant at free safety after the switch.

And the things I did in college was to keep my body fit, make sure my hips were still fluid and make sure I can make those open movements. Now that im in the NFL, I have all the time in the world to work on things like that. i don't see myself moving to safety. If i move to safety it's something I have to deal with, but I want to be a cornerback for life." There has been no cornerback taken higher than third in the draft, but Peterson could break that run. He hopes so, anyway. "That would be wonderful for me to break that (streak)," he said. "I'm a unique guy. I played punt return and cornerback. I'm 220 pounds. I'm fast. it would be my honor to come in and start something new ... When I get in the NFL I want to become a cornerback first, then I want to pursue the special-teams role after I get the defensive assignment down."
