A marriage counselor wasn’t needed last season to determine that cornerback Mike Jenkins and the Dallas Cowboys were headed for a divorce. Jenkins signed in the off-season with the Oakland Raiders and will be back at AT&T Stadium on Thursday to play the Cowboys. The 2008 first-round pick was the Cowboys’ best cornerback in 2011 but lost his starting job coming into 2012 when Dallas signed free agent Brandon Carr and traded up to draft Morris Claiborne sixth overall. Jenkins also was never quite right last year after he underwent reconstructive right shoulder surgery in the off-season that kept him from practicing. Feelings were hurt along the way as Jenkins did much of his rehab work in South Florida even though the Cowboys encouraged him to do it here. Jenkins said Tuesday that he’s happy with his new team. But despite saying that Thursday’s game will be like any other to him, Jenkins made it clear that some bitterness still remained from his breakup. Jenkins was asked if he’s regained his swagger in Oakland that helped him reach the Pro Bowl after the 2009 season. “My swagger and my confidence never left. My last few years in Dallas had nothing to do with swagger,” Jenkins said. “It was more of a personal vendetta that was going on around there, and I don’t care too much to talk about it.” Jenkins declined to elaborate, calling it “pointless” to “bring up old fire.” Jenkins was pushed for playing time throughout his career with the Cowboys by cornerback Orlando Scandrick, who is thriving this season with Jenkins out of the picture. The Cowboys signed Scandrick – a 2008 fifth-round pick – to a five-year, $27 million contract extension before the start of the 2011 season, but Jenkins never saw a second contract with Dallas. Asked Tuesday if he was envious of Scandrick, Jenkins raised the tone in his voice.
