I say David Barrett. Most people around here seem to hate the guy, but he's been a servicable corner who has occasionally SHUT DOWN guys like Andre Johnson. He allows a lot of completions in front of him and is certainly not very fast, I just think he is a decent corner who is underrated by Jets fans. He gets beat, but everybody gets beat. I see guys like Al Harris and Mike McKenzie, who are regarded as top corners, get torched often. Don't get me wrong, I don't want him starting 16 games opposite Revis, but I like him a lot in a rotation.
I think it's Justin Miller. Alot of people have written this guy out, but he is having a good camp and seems to have matured. He has world class speed and could be an excellent corner opposite DR.
