My opinion is he is going to be pretty damn good when it's all said and done. What I mean by that is he very well could end up being the best CB to come out of this years draft.
Now, that by no means says he *IS* the best CB in the draft. I think he is less developed than some of the others at this point. Without question though, there is a valid possibility his ceiling is higher than any of the other CBs in the draft. DRC is the other I believe could have the highest ceiling. In the first round, I take McKelvin or DRC before King though. They, I believe are more ready to take the field. I'm not sure King is even ready to be a 3rd cornor.
Of course as with any draft prospects, there is always the possibility of him being a bust.
