A couple of new mocks have come out and surprisingly they are for players I had thought were late first or early second round draft choices...

Charlie Casserly at NFL.com has us mocked to take safety Mark Barron of Alabama with our first pick...

While Don Banks at SI has us mocked to take cornerback Stephon Gilmore of South Carolina with our first pick...

If that were the case and Carolina actually drafted either with the first pick...who would provide the biggest and most immediate impact between the two?
