Cavaliers Owner Dan Gilbert Congratulates Mavericks, Rips LeBron James in Tweet

Cleveland Cavaliers owner Dan Gilbert is not a big LeBron James fan — for obvious reasons — and Gilbert did not hide his satisfaction with the fact that the former Cleveland Cavalier failed to bring a title to South Beach in his first season with the Heat.

Gilbert tweeted minutes after Miami lost to the Dallas Mavericks, 105-95, in Game 6 of the NBA Finals on Sunday night to give the Mavericks their first NBA title. He congratulated Mavs owner Mark Cuban and took a jab at James, whom Gilbert said was taking a "shortcut" by joining forces with Dwyane Wade and Chris Bosh in Miami.

James scored 21 points in Game 6, but struggled mightily in the fourth quarter throughout the series — with only 17 total fourth-quarter points in six games. He has yet to win a championship in two Finals appearances.
