i agree. i was sold on his natural CB ability from watching him in the senior bowl. he could be a very nice UDFA grab. he's got really good instincts and he's a competitor. and from all accounts he is a bulldog in special teams play. that is the recipe for a roster spot to be sure.
Don't get me wrong, he does have holes in his game. His biggest being that he can be shy about contact, which sucks but is also something a lot of corners are known for.
However, I do think that he is a "natural talent" and that his measurables don't tell the story. I would be WAY more worried about Captain at #2 than Burney at #3 though.
