It wasn't the Lakers defense that made Orlando shoot that way. LA's offense was ok, but aside from Kobe it wasn't fantastic, it only looked that way because the Magic shot under 30% from the floor. That's a real outlier from a statistical perspective. It's only an issue if it happens again.
LA's rebounding edge is a result of all those missed shots, and the fact that the Magic do not stay and rebound, but run back on defense on a miss. Not hitting outside shots most of the game killed them and allowed the Lakers to get and maintain a huge lead.
46% from the floor isn't that great. Consider that the Magic got to the line for 11 more shots and had 4 more steals. Turnovers were equal.
The addition of Jameer should help as the series goes on and he gets into better condition. Maybe Stan should shorten the time he's out there until he can manage better. They shouldn't need to rely on him to create their offense, he adds an extra dimension, but it's something that Hedo and Lewis do as well.
Really the Magic played fine in the first quarter, and should have kept playing the same way, getting into the paint and scoring. They got too many open looks from the outside, and settled for them instead of continuing to break down the Lakers interior defense. The Lakers have no answer for Howard, and couldn't stop him. It seems to me, the Magic had everything going the way they needed but couldn't hit a shot. I doubt very much that they will continue to miss from the floor like that. They could have played the same game and made 40% of their three's and been right in it.
