The latest mock drafts by Mel Kiper Jr. and Todd McShay both have Louisville's Calvin Pryor rated as the second-best safety in the draft.

And both believe he will be available when the Green Bay Packers pick at No. 21 overall.

But only one believes they will take him.

Just as he did in the first version of his mock draft released last month, Kiper has the Packers picking Pryor -- the 6-foot-2, 208-pound junior from Louisville -- in his Mock Draft 2.0.

Among Kiper's comments on Pryor were: "Pryor is a downhill safety who will fly up to the line of scrimmage and make plays. While he's got work to do in coverage, he's instinctive and athletic enough to get better there."

In fact, Kiper thinks there's a chance that as the pre-draft evaluation process continues Pryor could push Alabama's Ha Ha Clinton-Dix as the top safety in the draft.

There's no question that safety is the Packers' biggest need this offseason.

McShay has only one safety -- Clinton-Dix -- going in the first round but listed Pryor as the best available player among those he did not have going in Round 1.

In his first mock draft in December, McShay had the Packers taking tight end Eric Ebron, but now he believes the 6-4, 231-pounder from North Carolina will be gone by then.

In McShay's Mock Draft 2.0, he has them taking Oklahoma State cornerback Justin Gilbert. McShay acknowledged that cornerback is "not as much of a need position as tight end, safety, D-line and linebacker. So this is more of a value pick than anything else. Gilbert is the top cornerback prospect in a class loaded with them, and he is an absolute ball hawk with good size and the ability to press or sit back in coverage."

Cornerback would become a greater need if general manager Ted Thompson does not re-sign Sam Shields or releases high-priced veteran Tramon Williams.
