Jason Collins went through the sad routine yesterday of any player who gets traded in the middle of a road trip.

He went up to his room in the team hotel to pack his clothes, stayed overnight with family and friends in the area, and today caught a flight back to Boston to clean out yet another room.

Danny Ainge’s only trade yesterday, which sent Collins and the expiring contract of Leandro Barbosa to Washington for shooting guard Jordan Crawford, didn’t settle in well for Collins.

It was the way he received the news — via a call from Ainge only after he had received a text message from a friend and confirmed it with his agent.

“Business is a part of sport and that’s what happens,” said Collins, the hurt apparent in his voice. “I got a text message from a buddy of mine first, because it was on hoopshype, and then I called my agent and confirmed it. I got a call a couple of minutes later from Danny Ainge, so that felt good.”

The disappointment also came from getting traded by a team he chose over other options last summer.

“I could have gone other places, but that’s part of the business. It’s not the first time I’ve been traded. I understand everything that was involved in it,” he said. “For me, I have a responsibility to honor my contract and go on from there. I have to go upstairs, get my bags. I’m from here, so I can stay with friends and family tonight, and then pack up, go to Boston and get my stuff, and then we’ll see.
