if I had the choice of 3 CBs.. yah Dunta would be on it. He is different from other CBs in that he is a VERY capable CB that doubles as a strong saftey in his blitzing and tackling abilities.
He may be the only CB in the league that has the potential to get in your head like an SS or FS would.
This makes him not only talented.. but versatile. A useful tool.
And I havent seen him get REALLY beat since week 5.
