With the Oakland Raiders closing in on a trade for cornerback DeAngelo Hall, which likely would also entail a big-money contract for the disgruntled Falcons, our guess is that the Raiders would then strip the exclusive franchise tag from cornerback Nnamdi Asomugha.

But if Asomugha signs the one-year tender offer in an amount equal to the average of the five highest 2008 cap numbers for NFL cornerbacks, the tag is irrevocable — and the salary is fully guaranteed.

So our free, unsolicited, and likely unwanted advice to Asomugha is to sign the tender.  Right now.

Three years ago, cornerback Charles Woodson triggered a negative reaction from the Raiders by signing his franchise tender, presumably at a time when the team was thinking about removing it.

If the franchise tag is rescinded, the player immediately becomes an unrestricted free agent.  But since most of the big money already has flowed in free agency, Asomugha might be better off taking the one-year guarantee in 2008, and then hitting the open market in 2009.
