Would Nnamdi Asomugha have made difference?

IRVING, Texas -- The Cowboys did not hide their interest in adding cornerback Nnamdi Asomugha as a free agent in the early part of the 2011 training camp.

Asomugha ended up signing a five-year, $60 million deal, with $25 million guaranteed, the Philadelphia Eagles after the Cowboys were unwilling to go that high.

“It was an opportunity to improve ourselves if it worked out,” executive vice president Stephen Jones said. “But it didn’t work out.”

The Cowboys have allowed a 100-yard receiver in four straight games and have been burned by less-than-stellar quarterbacks such as Washington’s Rex Grossman, Miami’s Matt Moore and Arizona’s Kevin Kolb in important moments before a start-to-finish whipping by the New York Giants’ Eli Manning on Sunday.

While he is not having the Pro Bowl type of season he had in Oakland, would Asomugha have upgraded a secondary that has struggled lately?

“I don’t know,” Jones said. “It’s not over yet. We’ve got to play the Buccaneers. We control our own destiny if we win the rest of our games and we will see. A fair question.”
