WALTHAM -Glen ‘Big Baby’ Davis said on Tuesday morning that he has already put the biggest shot of his career in the past while also offering an apology of sorts to the 12-year-old boy with whom he collided moments after winning Game 4 at the buzzer.

“I’m a big guy,” Davis said at the Celtics shoot-around prior to tonight’s Game 5 at TD Banknorth Garden. “Imagine if my emotions are going so wild, and if I’m running by somebody, I don’t feel them. If I’ve hurt anybody or if I’ve done any harm to anybody, please forgive me because my intentions were just harmless.

“I didn’t see the kid,” he continued. “I’m a big guy and I’m emotional. If I had seen him, I would have picked up, rubbed his head and tried to make him feel better. I’m a big guy guy. I’m just sorry if I hurt anyone.”

Davis said he’s seen the highlight a couple of times but has moved on from it.

“You like to see it once or twice, but when you keep seeing it, you keep dwelling on it,” he said. “You keep yourself in la-la land and right now I can’t be in la-la land. We’ve got a game today. It’s how fast the quick turnaround is. That shot goes out the door. It’s history.”

As for the shot itself, Davis said he had never hit a game-winner like that one.

“That was my first,” Davis said. “That’s where dreams come true. That’s where good players turn into great players. Sometimes pivotal moments like that makes you understand the competitiveness of the game and just brings out the competitor in you. Hopefully, that’s a shot I can always look back on and a shot that not only boost my confidence and but also boost me playing in this league.”
