What makes you think that Sean Smith will be a better safety than a corner? Because some draftnik said that? Please prove a valid argument. Don't tell me just because he is 6'3 that he should be a CB - he has great man coverage as well as zone coverage skills and shut down Julio Jones in the real National Championship. Nnamdi is 6'2. Mel Blount who is arguably the best CB of all time was 6'3. You can be big and still be a very good CB.
