3. Montrezl Harrell
Nobody should deny that PER (and other aggregate metrics) can be a little wonky. We're not trying to knock Harrell. Still, it doesn't feel like he's the third-best player in LA Clippers history.
A few caveats apply here. Harrell typically squared off with second units. That allowed him to inflate his counting stats. Moreover, PER doesn't capture the fact that Harrell was a defensive tweener. He wasn't big enough to protect the rim, but he wasn't quick enough to contain the perimeter.
Let's focus on the positives. In 2019-20, Harrell averaged 18.6 points and 7.1 rebounds per game - good for a PER of 23.4 and the league's Sixth Man of the Year award. His 24.7 mark from the year prior was even more impressive.
Harrell was a dynamic inside scorer who could also finish pick-and-roll sets. It may be that PER overrated Harrell a bit, but that doesn't mean that he wasn't a highly valuable player for this organization.
