Manziel Says He's Not Ready For Opener Yet

 Johnny Manziel, so full of swagger and cool, understands his limitations. He's only a rookie.

And as the celebrity quarterback prepares for Cleveland's exhibition on Monday night in Washington, a game that could decide whether he or Brian Hoyer starts the season opener at Pittsburgh on Sept. 7, Manziel acknowledged he's still got a lot to learn.

"I don't think I'm ready for Pittsburgh right now," he said.

Manziel, though, was quick to point out that he's made progress during training camp, and he expects to get better running Cleveland's offense.

"I've only played one game, but the more and more you see it, the more you get familiar with it, the better it will be," Manziel said after practice Saturday.

Manziel and Hoyer will split time with Cleveland's first-team offense against the Redskins in a game being hyped as a nationally televised matchup between Johnny Football and RG3, Washington quarterback Robert Griffin III.
