Standing five rows directly behind the Heat's bench, the man in the blue  jeans, white T-shirt and filthy mouth launched an object that was  headed directly toward the back of James' head as the superstar sat  unaware watching his new team finish off his former squad. 
This time, it turned out to be knotted rally towel, which fell about  two feet short of striking James before it was swatted down by a Heat  security officer. Maybe that fan -- who was quickly whisked out of the  arena with a taser aimed at his back by police -- wasn't aiming at James  after all. 
Perhaps he was attempting to do everyone in the building a favor.  Because someone probably should have thrown in the towel for the  Cavaliers way before things got as ugly as they did in the fourth  quarter of Miami's 118-90 victory that was part coming-out party, part  confirmation hearing for James. 
To James' credit, he largely ignored the chaos that started when someone  threw a battery from the stands that landed right in front of the  Heat's bench. That drew a warning from the public address announcer. 
The battery was thrown right around the time when a man apparently  tried to rush the court from one of the tunnels leading to it but was  picked off by a security officer, which led to a scuffle. As the Heat's  lead grew, so did the craziness in the stands. One fan wearing a Heat  jersey was showered with cups of beer in the upper deck. He didn't duck.  Instead, he basked in the beer until he was escorted out. 
Then came towel man. Maverick Carter, James' business manager, left  his courtside seat moments later and had to be escorted through the  crowd by three bodyguards. James, meanwhile, was oblivious to his  surroundings. Or at least he did a remarkable acting job.
