There's a loose rule in journalism about not running every rumor you hear as hard news without at least making some attempt at checking it out. From the Miami Herald:
Team owners Micky Arison (Heat) and Mark Cuban (Mavs) didn't arrive by limo, helicopter or Range Rover. The millionaires both came by boat and docked on opposite sides of the arena. Cuban's Utopia II is nice enough -- if a bit modest, at 60 feet. Arison's Sirona III is a Shaq-sized monster, well more than 100 feet long. 'I think there's a little bit of boat envy goin' on,'' said Brad Morris, director of operations at the arena. ''I mean, compared to Arison's, Cuban's boat is pretty piddly.'' Morris said he heard Cuban had draped a ''Go Mavs'' banner across the boat earlier in the day and caused such a stir that the police were summoned. Oops. It wasn't there at game time.
From Mark Cuban:
How difficult is it to see what is or isnt right in front you ? Well guess what guys. I dont own a boat. Never have. Never will. I rented one once. Rowed one a couple times. Thats it. My apologies to the real owner of that boat who is getting pestered with helicopters and people trying to corner them.
Oops indeed.
