That all makes sense.
Guess what Dwight Howard is thinking about?
LA: Staples Center filled with Hollywood celebrities, warm weather all year, the possibility to be featured in even more commercials, TV shows -- who knows, even movies. Warm weather year round, nice beaches, mountains, etc. Biggest market in the country and he could be the new face of the biggest sports team in town. The new Superman, the new King of LA. You get to play alongside Kobe, "the second coming of Jordan" for the last few years of his career.
Boston: Cold year round, except the summer when it's humid and rainy. No celebrities except for the occasional Matt Damon or Ben Affleck sighting. Celtics are the 3rd most popular team in town, with a fanbase that is notoriously cranky and critical. The prestige of playing alongside Rondo is much less than that of playing next to Kobe, even if it's much nicer in terms of the style of basketball.
