Miami Heat owner takes, then deletes subtle Twitter jab at LeBron James

The NBA season is nearly half done, and the not-so-great Cleveland Cavaliers are one of the year's main talking points. 

Following LeBron James's homecoming and the acquisition of Kevin Love, the Cavs theoretically should've been one of the better teams in the NBA. But Cleveland is just one game over .500 and far from dominant. 

Miami Heat owner Micky Arison noticed, and seemed to take a subtle jab at King James in a since-deleted retweet on Twitter. 

Arison retweeted two Forbes Magazine links stating that Miami is the happiest place in America to work while Cleveland is the unhappiest, then wished a happy birthday to longtime Heat player Dwyane Wade. 

As of Saturday, though, Arison unretweeted his Cleveland post. Maybe he had a change of heart.
