– He's not Johnny Football. It's simply football, Johnny.

After a failed and flawed rookie season that was followed by a 10-week stay in a rehab facility, Browns quarterback Johnny Manziel said he believes he's grown personally and professionally. Manziel said he's committed and beginning to find his stride.

"Football," he said, "is my life."

Manziel spoke Thursday for the first time in training camp. He said he is a different player and man. Instead of last year's headlines, these days he's just one of the Browns.

"It's nice to come out here and wear any kind of shoes that I want and that's not the main story of the next day," Manziel said, smiling. "And that, for me, is a good thing. Now I can just come out and play and do my game and really get to learn — because that's what I needed to do."

Manziel backs up Josh McCown. But the 22-year-old said he's not worrying about his place on the depth chart.

"I want to show that I can really go out and play and that I'm making improvements, that I'm making strides to get better," he said.

"And then from there on, coach [Mike Pettine], everybody else, they make that call."
