WRF is a top need, but it is still just below OLB. QB I would move to P4, because Fitz still has two years left before we can release him without doing serious damage to our cap.
LT is a P4 need at most, with hairston still under contract. Should Bell be resigned, I would move it to P5.
CB is a P3 need, and yes, I would draft a 2nd OLB first if the right one is available.
