He’s been good. But all is not well with the cornerback. ARLINGTON, Texas — Mike Jenkins has been jogging around the practice fields at Valley Ranch and the football field at Cowboys Stadium the past three days. He’s been smiling — no scowl, no screaming at a mob of reporters. He talked about the NBA Finals. He gave a nod to familiar reporters. The facts are Jenkins is not showing up to the Cowboys’ voluntary workouts, only mandatory ones. He isn’t rehabbing in North Texas from a serious and complicated shoulder surgery. We don’t really know what Jenkins wants. We’ve got dribs and drabs from people close to the cornerback that indicate he wants a trade. We’ve been told he wants a contract extension. The Cowboys are not doing anything but supporting Jenkins’ rehab while saying he’s not going anywhere. They plan on using him extensively. So where do we go from here as the players head home for the next few weeks? Jenkins could report to training camp in late July and make the Cowboys happy. If he doesn’t, the team will be forced to either fine or trade him. It’s not a situation the Cowboys want — they’d rather see him on the field. His shoulder was so bad last season that he had trouble putting his shirt on and taking it off. He played through pain. It showed the Cowboys’ brass that he can play through adversity. One of the biggest things I remember defensive coordinator Rob Ryan saying when he first arrived was that he wanted cornerbacks to play with courage. Jenkins didn’t have that reputation, but he turned it around in 2011. He was active on tackles during the regular season. He first became injured trying to make a tackle in training camp, and that seemed to dispel the notion that he’s not a physical player. His recovery from a shoulder injury means he might not hit the field until late August. That’s just a guess. “I know he ultimately will get in a position to play because it’s not in his best interest [not to],” Cowboys owner and general manager Jerry Jones said. “I know that it’s just not in his best interest to not be ready to play. If it’s later, we’ll use him later.” If the Cowboys have to use Jenkins later, that’s fine because they have Brandon Carr, Morris Claiborne and Orlando Scandrick. In a way, that’s the trouble with this Jenkins drama. He was the Cowboys’ best corner last season, yet the franchise thought it was necessary to upgrade the position. Maybe Jenkins took the offseason moves as a sign of disrespect. Maybe Jenkins just wants to feel loved by the Cowboys. This entire offseason has gone peacefully for the Cowboys with the exception of Jenkins’ dispute. You can’t blame him for the way he feels; you just wish he would act a little differently. The Cowboys are not the enemy here, just a franchise looking out for its best interests, much like Jenkins is looking out for his. At some point this summer, the Cowboys and Jenkins will come to terms on whether he stays here or goes elsewhere.
