Cavs owner can’t help himself

Cleveland Cavaliers owner Dan Gilbert was quick to congratulate Mark Cuban and the Dallas Mavericks on their maiden NBA championship Sunday night — and he did not miss the opportunity to take a subtle shot at his former superstar LeBron James, either.

After James’ much-maligned move to Miami last year, Gilbert made a promise to Cavs fans, saying, "I PERSONALLY GUARANTEE THAT THE CLEVELAND CAVALIERS WILL WIN AN NBA CHAMPIONSHIP BEFORE THE SELF-TITLED FORMER ‘KING’ WINS ONE."

And after the Mavs wrapped up the series 4-2 with a 105-95 win in Miami Sunday, Gilbert had another message.

"Congrats to Mark C.&entire Mavs org. Mavs NEVER stopped & now entire franchise gets rings. Old Lesson for all:There are NO SHORTCUTS. NONE," Gilbert wrote on Twitter.

James struggled offensively throughout the series and failed again to make an impact in Game 6, despite scoring 21 points. He remained confident his day would come.

"The Greater Man upstairs know when it’s my time. Right now isn’t the time," he tweeted.
