Trent Cole is an inquiring mind. The veteran Eagles pass rusher shares a locker room with Michael Vick and Nick Foles, but he’s as far removed from -- and equally curious about -- the competition between his two teammates this summer to decide the first quarterback of the Chip Kelly era. He isn’t alone. Given the widespread impact felt by a decision this significant, he and other teammates who aren’t directly involved in the joust are still watching closely. It started during the spring camps. “Uh, yeah, we’ve been taking glances,” Cole said last month as the the Eagles prepared for their six-week break before training camp. “We’re curious just like anybody.” Training camp starts when rookies report July 22. The rest of the pack arrives three days later. The storyline that promises to capture daily headlines, both locally and nationally, is the face-off to decide who starts at the game’s most important position. Vick and Foles split first-team reps throughout the minicamps and organized team activities, but nobody has ruled out rookie Matt Barkley or even Dennis Dixon. The competition promises to place all of the quarterbacks (with the exception of G.J. Kinne ... no offense, G.J.) under the microscope every day at camp and become the dominant topic of the Philadelphia sports scene this summer, especially if the Phillies fizzle out of the playoff race. But the chatter won’t just be reserved to water coolers and sports-talk stations around the Delaware Valley. It’ll be the gossip around the Gatorade jug at the NovaCare Complex. Lines will be drawn, allegiances pledged. “We’ll see what happens,” said right guard Todd Herremans, one of several teammates directly impacted by the decision. “I have no idea what’s going to happen back there. I think there [are] at least three guys that will be able to run the offense for us.”
