BEREA, Ohio -

Fans might expect Cleveland Browns rookie quarterback Johnny Manziel to eat, sleep and breathe football 24/7/365, but that is not going to happen. More important, his coaches and teammates don't expect him to be that way.

Manziel spent Memorial Day weekend in Las Vegas after the Browns completed their first week of OTAs. He took his playbook on the trip to study during his plane flight, if not during down time in his hotel room -- which there was not much of.

The trip drew criticism on ESPN from former NFL quarterback Mark Brunell.

"It bothered me," Brunell said. "If I'm Ray Farmer and I'm the general manager of the Cleveland Browns, I want to know the future of my franchise isn't going to fly to Vegas every time he's got two or three days off."

Manziel was not responding to Brunell's comment, but he said he will not be swayed by public opinion.

"I don't live my life according to you guys (the media) or according to what other people think of me," Manziel said Wednesday after an OTA practice. "I'm going to live my life to the fullest and continue to be committed to this game and committed to what I need to be doing here trying to earn my place in this locker room, with these coaches and with this organization.

"If I want to go out and have some fun and it doesn't hinder what my main goals in life are, then I don't really care what anybody has to say."

Manziel has the support of his head coach, Mike Pettine. Pettine said he knew in advance of Manziel's Vegas Vacation, which included ringside seats at UFC 173, a poolside picture with Patriots tight end Rob Gronkowski and a bevy of bikini clad beauties plus a night of partying that ended with spraying champagne around a nightclub.

"He let us know that he was going," Pettine said. "My advice to him was 'Have fun.' He's a young guy. He's done everything we've asked. The playbook has not been an issue for him.

"I know a big deal was made of it. Internally, we have an expectation for all our players outside the building to act a certain way. It's really a non-issue. He's a man and we're going to treat our guys like that until they prove they need to be treated otherwise. He didn't do anything illegal. I'm not going to micromanage our players outside the building."

Left tackle Joe Thomas, a seven-time Pro Bowl player, said he has no problem with what Manziel did.

"That's who he is," Thomas said. "You can't expect him to be someone he's not. He's a 21-year-old kid in the offseason. I don't think anyone has any issues with it.

"If you were doing that the night before a game, then it would be a different issue, but it's the offseason. You need a chance to decompress and get your mind off of football because it's a long haul and the season is going to be a long grind, so you need to kind of let loose a little bit when you get the chance."
