WALTHAM — The Celtics  leave Wednesday morning to begin one of their toughest four-day stretches of the season. On Thursday, they play in Orlando, followed by a road game in Atlanta the next night.
‘Huge,” Glen Davis said  of the week. “These are big, big, big games. If you’re not a competitor, you don’t need to play in these games. This is a great opportunity for us to keep our win streak alive and also get better with playoff-contending teams. We’re looking forward to the challenge. Every game is big but these games are bigger.’
Speaking of Davis, he said he is on a new path when it comes to his former moniker – ‘Big Baby’
‘Big Baby will always be a part of me. But I’m going to put Big Baby on the shelf ‘ for now,’ he said.
Asked why Davis, No. 11, is leaning toward ‘Uno, Uno’ as a new nickname, Davis pointed toward Bengals wide receiver Chad Ochocinco . Davis doesn’t feel the need to formally change his last name, just his handle.
“Every sport has their version of nicknames,” Davis said . “He paved the way. Knock off or not, I’m a different player than Ochocinco. He plays football. I play basketball.”
Davis wouldn’t be the first pro athlete in Boston to follow the Cincinnati receiver’s lead. In 2008, Jonathan Papelbon  had ‘Cinco Ocho’ T-shirts made up sporting the reverse of the famous wide receiver, and representing the No. 58 on the back of Papelbon’s uniform.
