DALLAS (105.3 THE FAN) – Johnny Manziel said he’s “optimistic and hopeful” that he’ll be given another NFL opportunity.

“That’s really what I’m holding out for every day,” the Texas A&M Heisman Trophy winner said Saturday from Tony Romo’s National Fantasy Football Convention in Dallas. “I know the situation that I put myself in. I know … the mistakes that I made. I’m hopeful. I’m really hopeful. I think that I made some progress in that regard. But we’ll see. Whenever I get a call, I’ll do whatever I can to make the most of it.”

“I think the thing I realized over the past year and the thing I realized from being away from it is really how much you miss it,” Manziel said. “That’s all I’ve known for so long. It’s what I love to do. It’s hard. It’s hard sitting here going through OTA time and going through summer time and then getting ready to go through fall camp and not being part of it. But at the same time, I’m really optimistic and hopeful that I’ll get another chance. That’s really what I’m holding out for every day.”
