From what I've seen this, is where I'd be at with respect to the Jets needs.
top 2 tackles, and Milliner who are assuredly gone.
Ansah who is too raw and in between in size
Jordan, who i don't trust physically, at all.
That's how I would approach drafting in the top 20. So if traded back, or acquired a middle round pick, that's the board I'd be picking from.
