Why is everyone picking OKC?

So with game one of the Finals underway, I was thinking about how surprised I am that so many analysts and fans are picking OKC to win this series. I think it's because the Heat struggled with Boston (who many people have underestimated all year), the Thunder impressively disposed of the once favorite Spurs, and Chris Bosh's injury that kept him on the sidelines for almost a month. Because to be honest, I think Miami is the better team. Look, we all know Lebron and Dwayne Wade can put up 30+ any given night, but what really impresses me is how well the Heat pass the ball. Lebron and Wade are two of the best in the league at penetrating a defense and drawing extra defenders. Once in the lane Lebron, a top 5 passer in this league, and Wade, an able passer all his own, have shown an affinity for kicking the ball out to very able role players. As I watch this team play I am amazed at how many wide open shots guys like Chalmers, Battier, Miller, and Haslem get game after game. Not only can these guys hit the shot, but they know when to make that extra pass to get an even better look. This team's athleticism and high-flying ability often overshadows their overall experience. James and Wade are both making their third finals appearance. Battier is playing in his eighth playoffs after a national championship run in his final year at Duke. And we all remember Mario Chalmers' heroics against Memphis in the 2008 NCAA National Championship. People debate the importance of experience and often say talent is all that matters. But even if you're in that camp, this Miami team has just as much talent as the young Thunder, and the Heat roster clearly has the advantage in experience, save for maybe Derek Fisher. That has to count for something. And on the defensive side of the ball, Miami's athleticism combines with their length and intensity. Lebron James, in my mind, is the best individual defender in the league (no I didn't forget about Dwight Howard). He's probably the most athletic human being in the world, and unlike some superstars...cough, cough, Carmelo Anthony...he commits himself to defense. During the regular season, the Heat allowed only 92 points per game, fourth best in the league, which is extremely impressive given their desire to get out in transition, a characteristic that seemingly doesn't fit a stout defensive team (think Chicago and Boston). This is not to say that the Thunder's defense is bad, even though they were ranked 17th in the same category. And although home court advantage in the NBA is more important than in any other sport, if Miami can steal one of the first two games in Oklahoma City, they ensure a return to Miami with at least a series tie, and three straight home games awaiting them. This is the advantage of the Finals' 2-3-2 format. I'm not saying that the Heat should necessarily be favored, but I'm surprised that such an overwhelming majority is picking the Thunder. Perhaps I'm slightly biased because I predicted a Miami championship all season, but so did many people, including these same analysts who are now picking against them. Anyways, this first game will be important in gauging how this match up will turn out.
