There was no shortage of shock and surprise when Koby Altman, the 35-year-old, first-time GM of the Cavs, reshaped the team’s roster with three major trades on Feb. 8.

It was Altman and his staff who targeted Jordan Clarkson and Larry Nance of the Lakers, George Hill of the Kings and Rodney Hood of the Jazz. There was no directive from owner Dan Gilbert, no plea from James, no nudging from Lue, to go and get those players, specifically.

Everyone was wrong about Altman. Everyone.

“I think Koby did a heck of a job of understanding what our team needed,” James said this week, after the rejuvenated Cavs — to use an Altman word — beat Oklahoma City, 120-112.

“It just wasn’t working out for us, and he felt like, obviously you guys saw his quotes, he made the changes that he felt best fits our team,” James continued.

The Cavs enter the All-Star break as the talk of the NBA. They’ve won four straight, tore up half their roster and are being discussed again as a legitimate contender while playing with a renewed sense of energy since Hill, Clarkson, Nance and Hood arrived.
