Orlando's offense is way too gimmicky. They launch 3's and throw lobs to Howard. That is not a recipe for top tier success if you ask me. It's too reminiscent of Jim O'Brien. Sure, you'll win some games and shut some teams down with tough D. But I don't think you can win a championship that way.
Until the team and Dwight himself gets enough confidence in his post up game, they will not break through to true contender status. That's my two cents, anyway.
