LEBRON LEAVING MIAMI, RETURNING TO CAVALIERS: [Click on Thanks, Not Anger for my column off today's major Heat news] Heat owner Mickey Arison's reaction today probably mirrors that of Miami fans everywhere. "I'm shocked and disappointed," said the Heat's owner. James stunned much of the NBA and sports world today by revealing he will leave the Heat in free agency after four seasons and return to his hometown of Cleveland. The huge negative is offset only somewhat by the word Chris Bosh (and Dwyane Wade) will remain. James leaves Miami with two championships in four seasons but also leaves the Heat in a lurch, and scrambling to remain a power in his wake. What is your gut reaction to the news of James' decision? The disappointment goes without saying? But is there anger, too? Our poll question could as easily have been worded as this: On LeBron's first return to Miami in a Cavs uniform, what will be your reaction? Say how you feel about LeBron leaving and why you feel as you do.
