Prize free agent Nnamdi Asomugha will choose between signing with the Jets and Cowboys, reports NFL Network’s Michael Lombardi.

I am hearing that San Francisco, Oakland and the New York Jets are the three teams ahead of the pack in the sweepstakes for free-agent cornerbacks Nnamdi Asomugha and Antonio Cromartie.

NFL Network insider Jason La Canfora envisions a scenario in which free agent cornerback Nnamdi Asomugha ends up with the Tampa Bay Buccaneers, but it might have as much to do with the new CBA as it does with actual team needs.

Crossing teams off the list of potential suitors for Nnamdi Asomugha is really a more interesting endeavor than looking at which teams would be interested in the gem of the free-agent market.

Many NFL observers believe it’s a foregone conclusion Nnamdi Asomugha won’t be back in Oakland. Not NFL.com senior analyst Gil Brandt, who believes the team’s owner is a wild card.

Nearly every day of the locked-out NFL offseason brings about new ideas as to where the prize of the free-agent market, Nnamdi Asomugha, could end up.

There’s no shortage of opinions during this locked-out NFL offseason as to where Nnamdi Asomugha, the consensus top player available when free agency begins, will eventually land. Asomugha’s former team — the Raiders — are seldom part of that speculation.

What — if any — separation exists between Nnamdi Asomugha and Darrelle Revis as the NFL’s best cornerback?

It’s not a stretch to think that every team welcome the addition of CB Nnamdi Asomugha in free agency. As one of the NFL’s few elite cornerbacks, who happens to be in his prime, Asomugha is the gem of a free agent market that only builds in anticipation during the locked-out offseason.

In terms of sheer talent, Nnamdi Asomugha will by far be the hottest commodity of players who are expected to be available in the NFL free-agent market.

NFL Network’s Michael Lombardi has little doubt the Raiders’ chances of keeping Nnamdi Asomugha are slim.
