So far, Mozgov has lived up to expectations. He's averaging a career-high 1.6 blocks per game with the Cavs, and while their defensive efficiency ranking has only climbed to a still below-average 21st, it has improved from 105.5 points allowed/100 possessions before the trade to 104.3 points/100 possessions since. With Mozgov on the floor, the Cavs are 3.4 points/100 possessions better defensively than when he's sitting, and three of the four most frequently used lineups featuring Mozgov have a defensive rating of under 103, including the current starting lineup, which has an excellent 94.5 defensive rating. Mozgov's impact on the team's defensive performance is obvious, given the overall team defensive stats. But what is he doing, specifically, to cause this improvement? Is he actually protecting the rim in the way many expected him to?
To further put Mozgov's defensive impact in context, consider the drop-off when it comes to the Cavs' other bigs defending shots at the rim. Mozgov's 45.6 percent is a significant improvement over Thompson's 50.8 percent allowed on 6.9 shots per game, and his numbers put Love's (53.4 percent, 7.3 FGAs) and Varejao's (54.4 percent, 7 FGAs) to shame* Mozgov isn't just effective as a rim protector; he's vital if the Cavs don't want to be a sieve at the rim.
