After finally getting his start earlier this month when Brian Hoyer was benched, Johnny Manziel struggled as the starting quarterback for the Cleveland Browns… before suffering a hamstring injury that will sideline him for the remainder of the season.

For his rookie season, Johnny Football was limited to just 175 passing yards and no wins as an NFL starter. But, he’s owning up to his struggles… calling the season “a year of growing up.”

Manziel does feel, however, that it’d be unfair if the Browns give up on him now, after just a limited time playing.

“I don’t think it’d be fair to give up on somebody after seven quarters of football,” Manziel tells ESPN of his rookie season, finishing just 18-of-35 passing with one touchdown and two interceptions.

“If that’s what they are in the business for and what they intended on me coming in here doing, just giving them seven quarters, giving them a couple of games and then looking somewhere else, I don’t feel that’s a lot of commitment of sticking with somebody.”

Manziel admits that he must handle things differently going into next season, and that he was still in a “college mindset” last year, not taking the rookie learning curve seriously enough.

“It’s been a year of growing up for me,” the quarterback said. “It’s a job for me now. I have to take it a lot more seriously than maybe I did at first.”

With the current season over for him, Manziel tells ESPN that he plans to spend more time in Cleveland this offseason, but will get back to his native Texas and work out in California as well.

“I haven’t painted the greatest picture of me being in here and staying on top of my stuff,” Manziel said. “I’m sure the stuff off the field has negatively affected that. But I know, and what matters to me the most, is that guys in this locker room see that I’m working…This is my life and my job and I’m 100 percent committed to that.”

While he plans to focus more, he says he’ll still flash his signature “Money Sign” on the field next season. “You can’t suck all the fun out of the game,” Manziel said.
