Following their 103-95 victory over the Toronto Raptors Wednesday night, James and several of his Heat teammates stayed in the visitor's locker room at Air Canada Centre to watch the final minutes of the Cavs' stunning 104-99 upset of the Lakers in Cleveland.
"Good for the Cavs," James said. "You definitely didn't expect the Lakers to have another letdown in Cleveland. But I've played with a few of those guys in Cleveland and they want to win."
James' reaction was measured and intriguing considering his comments the last time the teams met last month. While in Los Angeles with the Heat to play a game against the Clippers the next night, James made waves when he seemed to take a shot at his old team during their historic 55-point loss to the Lakers.
"Crazy. Karma is a b----. Gets you every time. It's not good to wish bad on anybody. God sees everything!" James tweeted at the time.
The next day, James said: "It's just how I was feeling at the time. It wasn't even a comment from me, it was someone who sent it to me and I sent it out. It wasn't toward that team."
This time, his comments were favorable when asked about his old team's big victory. He said the Heat can take a lesson.
"It's the NBA, if you don't show up on any given night, one team has to lose," James said. "We should take that to heart. We can't just show up and expect our talent, who we are, [to be enough]. You've got to go out there and execute and play."
