LeBron James had 34 points, seven rebounds and five assists in 39 minutes in the Cleveland Cavaliers' 108-98 home win over the Oklahoma City Thunder.
"We've improved, mentally more than anything," LeBron James said.
The Cavaliers have won six straight games.
"We're a confident bunch, but for us, we're a humble bunch," James said. "It's one game, against a very experienced team, a very talented team, very good team that's been together for a while and it shows that we can match up with that caliber team."
"I felt the atmosphere was a playoff atmosphere," Blatt added. "I'm glad we responded well to that kind of matchup."
