You know you’re good when a pair of NBA veterans curse your performance after you lead your team to a win on their home court.
Kevin Durant  is that good — and then some.
He scored from every spot on the court, including the free throw line — where he made all 15 attempts. When all was said and done, the Celtics  watched him pour in 37 points in Oklahoma City’s 109-104 win over the Green on Wednesday at TD Garden.
‘It’s a team job to help out, period,” Rasheed Wallace  said. “No matter whether it’s him or any other type of NBA All-Star, it’s a team effort to help out. It was a [pain], honestly. Helping Paul [Pierce ] and Ray [Allen ] out, it’s just a team thing. Got to stay with him.’
As for those 15 free throws, compare that to the fact the Celtics as a team made just 13-of-17 attempts the entire game.
‘I thought we were playing Michael [expletive] Jordan tonight the way he was getting the whistle,” Kevin Garnett  added. “Durant damn near shot more free throws than our whole team.’
‘We’ve grown, we’ve grown up,” Durant said. “We’ve added a lot of different pieces since our first year, me and Jeff. So it’s good to come in here and beat a team like Boston — a great team, a championship team like them. It’s all about moving on from here.
‘It means a lot for us, and like you say gives us confidence. We’ve got eight more games left, so we’ve just got to keep plugging away and keep pushing. This is another step for us. We’re happy with this win, but tomorrow we’ve got to let it go and get ready for Dallas.’
Maybe most impressive is the fact the Thunder shot 50 percent, 10 percent less than their opponent — on their opponent’s home court — and still managed to win.
‘If you want a tape about how to score the basketball, you’ve got to watch this game,” Durant said. “They scored it in a variety of ways and we scored in a variety of ways as well. Our point guard did a great job of starting us off early, getting to the rim and opening things up for everybody else. It was a great game as far as offensive is concerned. We’ve just got to work on our defense from here.’
Glen Davis  was one of the last Celtics to give his take on Durant on Wednesday, and he didn’t even need any dirty words.
‘He’s a problem because you’ve got to pay attention to him,” Davis said. “You’ve got to make sure he doesn’t beat you, and he had a big game tonight. We’ve got to get him out of his comfort zone and make sure he doesn’t have 37, but he did.’
