Dwight Howard was easily the best center in the NBA in the 2012 off-season when he thought Orlando wasn't worthy of his game, so he whined, got his way, and headed off to the Lakers empire, settling in with veterans Steve Nash and Kobe Bryant. Everyone expected Howard and LA to dominate the league, and easily grab yet another title. Well, it didn't necessarily work out that way. They squeaked into the 8th spot in the West, only to get swept by the Western Conference champion Spurs in the first round of the playoffs. Howard didn't have the season he wanted to, but still tallied 17.1 points and 12.4 rebounds. Luckily for Howard, he is faced with a good situation with his contract. Either he comes back to the Lakers where he could take over the organization with Kobe on the brink of retirement, or he could go elsewhere and contend for a title. With less stress and ridicule, Howard is sure up for an improved season.
On the other side, Roy Hibbert is currently dominating the Miami Heat front court, giving his team a chance at their first Finals appearance since 2000. Hibbert has really shown up the second half of the season after a horrid start, and has made even more believers in the playoffs. Hibbert had good series against Atlanta and New York, and has now put up multiple 20+ point and 10+ rebound games against the Heat in the Eastern Conference Finals.
If Hibbert carries his current play over to next season, there is no doubt he will be butting heads with Howard for the best center in the NBA, but right now, I think Howard has the edge. He just has more experience and really bullies guys around in the paint. One question to ask is, can he stop Hibbert's deadly jump hook that has made Heat fans sob?
