Don you're right. It is easier for a white player to be a running back then cornerback. There are all kinds of accepted running types: sppedy guys, shifty guys, power runners, guys who can read blocks, but there is only ONE type of cornerback: a small, quick, black player, that is dumb as a box of rocks, gets burned regularly, can't catch a ball to save his life and draws PI's at the wrong time. There are virtually NO exceptions to this sterotype so in some ways it is a tougher nut to crack then running back.
