It was only a week ago when Byron Scott walked into the Cavs’ locker room and told the players he hoped it was the final time he had to address issues regarding effort and energy level.

He thought they had finally opened their eyes to life in the NBA, understood teams have to play hard the whole night regardless of who is hurt and who is dressed for the opposing team. He thought his players had finally grasped the importance of effort and energy.

He was wrong.

“They haven’t learned,” Scott said Monday. “That’s obvious. They haven’t learned.”

All of the progress and momentum from the most recent three-game winning streak was swept out of Quicken Loans Arena with Monday’s embarrassing 100-92 loss to the hapless Minnesota Timberwolves.

It was just their third win in their last 18 games and it ended an eight-game losing streak on the road. The Timberwolves are without six regulars, including two of their top three leading scorers. But they didn’t need Kevin Love to beat a Cavs team that was completely disinterested in playing defense.

The Timberwolves shot 64 percent in the second half and made 10 of their first 11 shots to start the fourth quarter. Luke Ridnour scored 13 of his 21 points in the fourth.

“It was terrible in the second half,” Scott said. “I wouldn’t even call it defense.”

Kyrie Irving had 20 points and seven assists, but limped off the court late in the second quarter when he rolled his ankle after landing on Alexy Shved’s foot on his follow through off a shot. Irving returned for the start of the third quarter, but made just 1-of-5 shots in the fourth.

He was getting treatment after the game and was unavailable to speak to reporters, although the Cavs said the ankle isn’t expected to be an issue going forward.

Tristan Thompson had 16 points and nine rebounds and Dion Waiters had 12 points and didn’t miss a shot. He made all six of his attempts, but also turned it over six times and didn’t play at all in the fourth quarter.
