According to John McClain (not that one) of the Houston Chronicle, the Houston Texans have intensified their efforts for Nnamdi Asomugha "once they realized they could redo contracts" to free enough cap space. McClain reported Wednesday night that if the Texans couldn't sign Asomugha, then they'd make every effort to sign Bengals cornerback Johnathan Joseph, who appears to be favored for the Detroit Lions. Though it's free agency and anything can, and will, happen.
The reason we're bringing this up is because Johnathan Joseph's "decision" is largely based on Nnamdi Asomugha's deal with whomever he signs with. The San Francisco 49ers recently freed $15.7 million of cap space with the reported release of cornerback Nate Clements, which brings the 49ers into discussions for Asomugha. There's a chance that San Francisco could jump into the bidding for Joseph with the cap space savings as well.
As of this posting, as far as we know, the Bengals are still in the hunt to re-sign Joseph. They're just having to fight off the Houston Texans and Detroit Lions in the meantime.
