It's not that he thinks Rose is terrible at defense, he just thinks Thibodeau should get all of the credit for any defensive improvement, and Rose should get none. That's a little absurd. Problem is, there isn't a really good way to determine how effective a player is defensively. Going by straight defensive rating, Boozer is in the top 10 (along with the rest of the team, practically). Going merely by the difference in team defensive rating when a player is on the floor vs. without, Rose is the worst defender in the NBA, and Howard is in the bottom 10. No, the problem is that the award is subjective and this dude took a stand a long time ago and now has to search out ways to make it seem right. That compounded with the fact he is the inventor of a decidedly flawed statistic that shows Derrick in a negative light give him little choice but to make his stand. The problem is also that we Derrick Rose fans are super, giddily annoying and when someone presents opinions that are anything but completely positive, they get a lot of attention from us in the form of page views and more generated discussion. Seriously, we Rose fans are almost intolerable in our devotion and even though he deserves the positive attention, from a rhetorical perspective, we cause a lot of people to form adversarial opinions based mostly on how over the top we are.
