They could send him to Houston in the west, even if it's just a rental
They could send him to New Jersey, in the Atlantic division
But if they send him to Atlanta, Orlando won't win a division for years to come. Horford isn't putting them over the top against the Heat and Howard-Smith Hawks.
Maybe I'm in denial
But forming a second super team in your own division really kills your chances of doing anything. 8 games a year against the Heat and Hawks... 8 losses if the Hawks get Howard-Smith(-Paul?)
