Panthers coach Ron Rivera doesn't understand the assertion that you can't draft a cornerback first overall. Many believe LSU defensive back Patrick Patterson is the best player available in next month's NFL Draft. "Why can't you take a corner first?" Rivera said. "A shutdown corner, or a very, very good corner who can harass the receivers, throw off their timing is important as it is because it’s turning into a passing league. How is he going to impact your defense? Can it also help the offense? There are a few really good ones out there. Does he help our pass rush? Does he help get the ball back and get our offense back on the field?"
