When Eric Berry was playing pee-wee football, he was a center (Seriously). By the time he hit high school, he was playing on both sides of the ball -- defensive back and quarterback.
In fact, he was the No. 1 cornerback recruit coming out of high school, according to Rivals.com. If you check out the video above, I think the Chiefs may have a wildcat option on their hands.
