The Blazers made it back-to-back defeats, leaving them second in the Northwest Division.
The coach told reporters: "It was a disappointing game, needless to say. We got off to a slow start. We caught a team that's trying to put it together. They're on a roll and they're playing very well. They showed that in the first half. I thought defensively in the second half, we did an excellent job but the offense didn't quite catch up with it. The hole was too big.
"I think we can move the ball better. We've gotten away from the ball movement that's important for us. We need each other to help each other particularly on the offensive end. It's a hallmark of what's gotten us to this point. I think it's somewhat human nature for players to, everybody has a lot of confidence in themselves and when things are going poorly, they want to help the team.
"We've played a lot of games lately. We've done a lot of traveling. No one likes to use fatigue or the schedule as an excuse, but it is a reality. We need to catch our breath, get our bodies right and be ready to play Saturday."
Portland host the Toronto Raptors on Saturday.
