I don't think it was that much of a reach, if a reach at all. I did consider, strongly, taking Rogers and would have been happy with him, but took Jackson because I think he could start right away, not that Rogers couldn't. I know that's not saying much considering the Chiefs defense. I think it also may help that he practiced against Braylon Edwards and Steve Breaston, plus he has some versatility given that he has played some safety.
I looked at Browner too, but he is a bit raw, and the Chiefs need help now. I also considered seeking a trade down given the number of quality corners available, but in the words of John McClain, decided not to try and get cute. Given the choice I would have preferred Jones over Jackson or Rogers.
