Billy Davis, by all accounts, is an excellent defensive mind.

Is he a miracle worker, too?

Davis, the Eagles’ new defensive coordinator, has already heard the scuttlebutt about fans wondering if he holds the key to unlock the harnessed potential of cornerback Dominique Rodgers-Cromartie.

It was with Davis as his defensive coordinator in 2008 that Rodgers-Cromartie made the Pro Bowl as a rookie after the Cardinals drafted him 16th overall. He had picked off four passes, racked up 157 interception return yards and returned one pick 99 yards for a touchdown.

Davis was fired after the season, and Rodgers-Cromartie has since had some productive seasons but was largely a disappointment in his past two years with the Eagles. As the front office mulls whether to re-sign the enigmatic corner or let him walk in free agency, the potential reunion of Davis and Rodgers-Cromartie is viewed as a good reason for the organization to hang onto the 26-year-old defensive back.

“That I can’t answer because, again, I’m just new in the building,” Davis said Monday when asked if the team should keep Rodgers-Cromartie. “Coach Kelly and I, we will make those decisions.”

But Davis seemed to suggest that his history with Rodgers-Cromartie could help influence the team’s decision. At the very least, he spoke highly of his former player.

“I know DRC. We drafted him,” Davis continued. “As a young guy he went to to the Pro Bowl. He made a lot of plays and we had some success in Arizona with some pressure packages and got a lot of turnovers and we created some defensive scores and Dominique was part of that.”

Rodgers-Cromartie is just one of several veterans - especially in the secondary - whose fates will be decided on in the coming weeks and months. Michael Vick already took a major pay cut to preserve his roster spot, and some others might not even get the opportunity to come back on a reduced salary.
