eighth-best PER in NBA history. Wilt Chamberlain surpassed it three seasons from 1961-62 to 1963-64 (31.7, 31.8, and 31.6, respectively). Michael Jordan did it in 1987-88 (31.7) and 1990-91 (31.6). LeBron did it in 2008-09 (31.7) and 2012-13 (31.6). That's it.
I'm fully aware that Davis has played in just 53 games so far -- only Westbrook has played in fewer (49) -- and that his team is dangerously close to missing the playoffs, but his high standing in these efficiency metrics on a team low in the standings relative to his MVP contenders warrants some deep consideration as to what the most valuable player actually means.
