A.J. McCarron is on a mission to earn the first opening day start of his NFL career.

The former Alabama star appears to be in favorable position to do that after signing with the Buffalo Bills this offseason. McCarron will have to beat out second-year man Nathan Peterman and the Bills’ first-round pick, Josh Allen. So far, McCarron shared first-team reps with Peterman.

On Friday, McCarron addressed the quarterback battle during the Bills first of 3 weeks of organized team activities.

“It’s fun,” McCarron said. “You compete. You know, I’ve shared reps before. But it’s fun. We’re out here, everybody’s really learning, especially, speaking for myself, just trying to get timing with guys — first live action. But it’s been fun. And it’s always fun to compete.”

McCarron is right about sharing reps. He shared reps with Andy Dalton in the first 4 years of his career at Cincinnati. His new situation is obviously much different.

He signed a 2-year deal with the Bills after they traded starter Tyrod Taylor to Cleveland. McCarron, despite the fact that he only has 133 career passing attempts, is suddenly the veteran of the bunch.

He seems to be enjoying his change of scenery.

“They’re great dudes,” McCarron said. “Nate’s like a walking angel. He’s one of the nicest guys you’ll ever meet. Josh has been awesome to work with. I’m trying to help him in every way I can. We have a really good room. It’s fun to be a part of.”
