Sometime over the course of the year, someone realized, "Hey, James Harden doesn't play very good defense," and made a YouTube video to illustrate it. Truth be told, Harden has never played particularly good defense—and worse, he's never really shown an interest in playing good defense—but once that YouTube video and subsequent YouTube videos started to surface, people started to ask Harden about his defense. And they've asked him so much that, at some point, he's going to have to take a good hard look in the mirror and figure out how he wants to address his defensive shortcomings.
In the meantime, the good thing is that Harden doesn't struggle to put up points and he's going to continue to knock down big threes, drive the lane for buckets, and find ways to score. If he wants the Rockets to be a true contender, though, he's going to need to fix his defensive issues. It's the only thing preventing him from landing closer to the top of this list.
