Ya, he will get a few this year but the world is full of people who never reach their potential. So if every game he doesn't get the TD and taking into account your statement does that mean that he has failed?
No, the Lakers did not get LO for TD's, they got him to compliment Kobe and play a role similar to Pippen. Nobody in the franchise has ever asked him to do that, so no failure if he doesn't.
