Do you think Lebron James still has a lot of holes in his game?

I'm a Lebron fan, and many would argue him to be a top 2 player in the NBA (Kobe being the other), but to me it still seems that most of his points still come from bull-dozing his way to the hoop. His outside game (while improved some) and free throw shooting is still suspect to long droughts. It seems he's relying too much on athleticism, and I sometimes worry how his game matures as he ages when his athleticism would begin to wane. The way his game is now, he's more prone to injury. He's still young tho. Would do you guys think?
