Danny Ainge doesn’t drink alcohol, but he’s having a shot of reality with his beverages these days.

He has a genuine good feeling about his Celtics as they lug duffel bags filled with question marks through the last four regular-season games and into the playoffs. But the president of basketball operations is well aware the odds are not smiling kindly on his lads as they take the court against the Heat in Miami tonight — and beyond.

Even with both Paul Pierce and Kevin Garnett traveling to Florida, the two stars are battling ankle issues and will not play tonight, according to the team. (Dwyane Wade, who has missed six straight games with right knee soreness, expects to play for the Heat.)

In terms of psychological edge, the best thing the Celts may have going for them in a week is they may catch an opponent looking beyond their blip on the screen.

“I don’t know,” said Ainge, pondering the point, then reaching for real. “Usually when you’re under the radar and you have low expectations, it’s because you’re not as talented as the teams you’re playing. So I don’t know if that’s good or bad.

“We’ve been the favorites in a lot of series over the last years, and our guys have responded to that. This will be a chance to see what our guys are made of being the underdogs.”

Ainge then commenced with what would be considered stock talk from a guy at the top of an organization. But even in this case, he didn’t dodge the harsher facts.

“I love our team going into the playoffs,” Ainge said. “I think our team has good chemistry, we have a lot of resolve and I think they’re fun to be with.

“No matter who we play in the first round is going to be an amazing challenge for us, and we’re going to have less room for error than the team we play. We have to be on top of our game.”
