It took a broken thumb and a $25,000 fine to convince Glen Davis  to shed the identity he carried into the NBA.
But now, Davis wants a new nickname. He wants to leave Big Baby behind.
‘I’m not a Big Baby anymore,’ he said. ‘ I’m not feeling that anymore. You got that? No more Big Baby.’
So what does he have in mind?
‘Call me ‘Uno Uno!’ Yeah, I like that,’ he exclaimed after a reporter suggested the moniker. ‘’Uno Uno,’ that’s my new name.’
Big Baby represents a past from which Davis wants to move on. It’s a past that includes fighting in a car during the preseason and yelling obscenities at a fan just last week. He appreciates the opportunities he has been given by the Celtics  organization and never wants to revert back to the player who had to be granted second ‘ and third ‘ chances.
‘Being Big Baby, I just realized throughout my life I’ve been called Big Baby, and throughout my life I’ve been going through different changes. So really, I’m not Big Baby,’ he explained. ‘You know, it’s like I’m in a cocoon and now I’m coming out as a different player and as a different person also. Basically just the fact that the new person is growth, so you want to shed that Big Baby off. You want to be perceived as something else, not the past.’
To Rivers, Davis’ personality has nothing to do with the name he goes by. Regardless of whether or not he is Big Baby or Uno Uno, he is still a young player who is learning his way in the league. Davis asked that fans believe he is not a bad person or a troublemaker, and Rivers echoed his request.
‘He’s young, that’s the one thing I keep saying about him,’ he said. ‘He has to grow up in front of a lot of people where most people his age don’t. He’s not a bad kid. We just have to give him time. Some you don’t, some you do and he’s one you do.’
So while Davis figures out who he is and who he is going to become in the NBA, he is turning to his veteran teammates for advice along the way.
‘I look up to a lot of these players on this team and Ray Allen  gave me some great advice,’ he said. ‘The 26-year-old man has to think for the 36-year-old man. The 36-year-old man has to think for the 46-year-old man. So every decision I make is more than just today.’
