---Where Johnny Manziel goes, the spotlight follows, but head coach Mike Pettine and the Cleveland Browns continue to pledge their support of the fun-loving rookie.
The confident quarterback from Texas A&M spent part of last weekend -- time off for the Browns -- sipping champagne while floating on an inflatable swan in a swimming pool at Club Rio in Austin, Texas, where the "X Games" were staged.

---Indianapolis Colts owner Jim Irsay would not speculate on a possible NFL suspension after his arrest three months ago but did say that he would submit to random drug testing with local authorities and offer the results to the league.
Irsay spoke Monday for the first time since he went into rehab after he was arrested during a traffic stop in March when he failed multiple field sobriety tests and was in possession of nearly $30,000 in cash. He refused to apologize for his actions.
"I don't think that's something I'll address right now," Irsay said. "There are certain things I want to say that I can't say. We need to let the process go forward and I'll address that later. I'm a human being; if there's something I have to apologize for, I would, but at this point, it wouldn't be appropriate."
---Arizona Cardinals cornerback Patrick Peterson said he will not skip minicamp or training camp in a contract holdout.

Peterson, under contract through 2015 after Arizona picked up his player option for his fifth season, is in line for a huge raise with the market set by several significant deals this offseason.
