Browns OC: 'Manziel is putting himself in a position to be a quarterback in the NFL'

Cleveland Browns offensive coordinator John DeFilippo has spent only a short time with Johnny Manziel, but so far, he likes what he's seen.

"Johnny's been great,'' DeFilippo said after the second rookie camp practice Saturday, according to Mary Kay Cabot of the Cleveland Plain Dealer. "He's been fantastic. What he wants to talk about, before he stepped foot back in this building is his business. All I know is Johnny the football player, and he's been awesome. He's been working hard, very hard with myself and (quarterbacks coach Kevin O'Connell), and doing what we want him to do on the field."

Manziel was discharged from inpatient rehab April 11 after 10 weeks, and all indications are that he's been making positive changes to his life off the field.

"All I know is this: from the moment he stepped in this building from the last two weeks, he's been nothing but a consummate professional,'' DeFilippo said. "He's spent every hour that he's been allowed to spend in this building. We give them worksheets every Tuesday and every Friday, and they're done to the unbelievable detail that we need an NFL quarterback to do. From that standpoint, like I said I can't predict the future, but all I can do is tell you right now Johnny Manziel is putting himself in a position to be a quarterback in the NFL."

DeFilippo, who found success with quarterback Terrelle Pryor in Oakland, stressed that he won't make any drastic changes to Manziel's playing style.

"I'm the last guy - the last guy - that's going to take Johnny Manziel's athleticism away from him, " DeFilippo said. "I will not do that. I refuse to do that. Okay? And I told Terrelle Pryor the same thing. 'That's part of your game. Now, we need to refine the other part to make you the complete quarterback.'''
