NEW YORK — Doc Rivers  had a prediction of his own Wednesday night, less than an hour before Game 5 at Madison Square Garden. Reminded that the Celtics  have erased historic deficits in the past, such as being down 2-0 and 3-1. But neither they nor any NBA team in history has come all the way back from 3-0 down to win an NBA playoff series.
How appropriated would it be for the Celtics to be the first?
“I think so,” Rivers said. “I think that would be wonderful, and someone’s going to do it, and I want it to be us since that’s the situation we’re in. But someone will do it and I really want to be a part of that.”
But that’s where the talk and statement-making ends for Rivers.
Kenyon Martin  made good on a prediction that he would have players show up in all black for the Celtics’ funeral Wednesday, all players arrived in black suits and ties. Asked for a reaction to the Knicks showing up in their dressing room all wearing back, Rivers fired back, “So did I.”
The playoffs have always been putting actions before words.
Rivers knows this better than anyone. He knows when teams talk like the Knicks did after Game 4, that’s usually a sign of immaturity and sometimes panic.
So, when asked if he thinks at all about what the series would be like if the Celtics had Rajon Rondo , Rivers used the chance to jab back at the Knicks.
“I don’t think that,” Rivers said of Rondo’s absence and the role in the series. “I don’t use that as a reason. Just like the Knicks probably shouldn’t use that the reason we won was because J.R. Smith didn’t play. But they did.
“That’s what they should do. I hope they expend it all. I don’t really care. We just have to come out ready to play. They’re at home, they’re going to try and feed off their crowd and all that but at the end of the day, it’s going to be between the lines. It’s not going to be what anybody out in the crowd says or does. It’s going to be between the lines.”
Reminded of his one-game-at-a-time mentality heading into another elimination game, Rivers added, “We have no choice. We need to go one possession at a time, really. It’s what you really need to do in the playoffs. To be really great, you need to be one possession at a time.”
More from Rivers shootaround and pregame:
On Jeff Green ‘s emergence as a go-to scorer: “I’ve got a feeling they probably went to Durant in Oklahoma City. At Georgetown, he was the guy. He got them to the Final Four. He’s been there before.”
“If he plays well, he will. If he doesn’t, then he’ll do it again next year. If he plays well [next year], then that will be. I don’t try to put too much on any one game or one series. He’s so young, he has a long career. The sooner he gets it going, the better for everybody.”
On whether Green is back to full strength after heart surgery: “I don’t know about this surgery. It’s usually ankles, knees and things like that. I don’t know is the answer. I would say usually in that case but it’s not anything I’m thinking about right now, to be honest. It’s not my concern or thought.”
On what experience in playoffs means: “The playoffs are the best tool of teaching you can use for all the players. Even the veterans learn in the playoffs because you really do understand that every possession matters in a game and not the last possession when you decide to focus on that and then you realize it’s too late.
I think everybody, even the guys who aren’t playing a lot, they see it, they see the intensity that if you want to be great, that you have to play at, consistently.
On Avery Bradley , his struggles and his matchup this series with Raymond Felton : “I think it spills over to the defense at times. You’re human. If you’re not making shots and you’re getting down on that, that takes away energy from you, on both ends. I think overall, he’s fighting through it. I think he’s coming out of it. He made his first shot the other night [in Game 4] and didn’t make another one. But he made his first shot. More importantly, I didn’t think he hesitated on any of the other shots. That’s all we want him to do. For us, he’s our defensive player. The offense will come.”
