As James' former team was absorbing a 55-point road loss to the Lakers Tuesday night, the Akron native fired off a message on his Twitter account that seemed to be directed at Gilbert.
James wrote: "Crazy. Karma is a --. Gets you every time. It's not good to wish bad on anybody. God sees everything!"
In July, after James announced he was leaving for Miami, Gilbert wrote a scathing letter to Cleveland fans questioning the two-time MVP's character and predicting he would take Cleveland's curse with him "down south . . . James will unfortunately own this dreaded spell and bad karma."
James and Gilbert have been at odds since the summer, when James decided to join forces in Miami with fellow stars Dwyane Wade and Chris Bosh. In an interview with The Associated Press in the hours after James' announcement during an hour-long television special, Gilbert accused James of quitting in the playoffs the past two seasons.
And although both insist they've moved on, James' tweet seems to show he has lingering bitterness toward Gilbert.
His social network message was poorly received in Cleveland, where fans still feel betrayed by his spurning them. It's bad enough the Cavs are struggling, but James decided to kick them when they're down.
And with 20 losses in their last 21 games, they can't get much lower.
The blowout was especially disturbing to first-year Cleveland coach Byron Scott. "I thought that was embarrassing," he said. "I told them at halftime, 'You look scared. You look scared to death.' "
