Capturing defensive value and impact through analytics, most NBA numbers-crunchers will acknowledge, still is pretty challenging. Compared to how those folks feel about their ability to track, measure and assess a player’s or team’s offensive components, the other side of the ball remains an inexact science.
But the NBA clearly is trying, as evidence by the supporting info provided with the release of its All-Defensive teams for 2014-15.
Consider what was noted about San Antonio forward Kawhi Leonard‘s finish as the first team’s top vote-getter. The league’s release read:
Leonard teamed with [Tim] Duncan to help San Antonio hold opponents below 100 points per game (97.0) for the 20th consecutive season. Leonard averaged career highs of 5.9 defensive rebounds and a league-leading 2.31 steals for the Spurs, who were 5.1 points better per 100 possessions on defense when he was on the floor than when he was off the floor, according to NBA.com/stats.
Most of those are old-school stats, no big deal. But the use of defensive rating and on/off numbers is an indication that even the so-called expert voters don’t have to guess, go by reputation or rely solely on anecdotal observations anymore.
Similar numbers were invoked supporting Golden State’s Draymond Green and Memphis’ Tony Allen as elite defenders:
The Warriors allowed a league-low 98.2 points per 100 possessions, a defensive rating that dropped to 96.0 with Green on the court and increased to 102.1 with him off the court. Memphis’ defensive rating was 8.7 points better with Allen on the floor (94.9 per 100 possessions) than with him off the floor (103.6 per 100 possessions). Green ranked 14th in the NBA in defensive rebounding (6.7 per game), and Allen finished third in steals (2.05 per game).
Also of interest in the announcement of the honors was the order of finish. The top three finishers in DPOY balloting – Leonard, Green and the Clippers’ DeAndre Jordan – all made the first team, but because positions are specified on the all-defensive ballots, Allen actually had the third-most points. First-team votes count two points and second-team votes count one.
With four guard spots available vs. two center spots, Allen had a better chance to appear on more ballots overall. Allen received 88 firsts and 31 seconds for 207 points, while Jordan went 84-19-187.
None of the breaks between first-team and second-team selections, or second-team and “others,” was close on points. But there were a couple quirky finishes. For instance, LeBron James received six first-place votes at forward to Duncan’s five, but missed a second-team forward spot on points, 64-47. Russell Westbrook got 13 first-place votes at guard, more than John Wall‘s seven, but also lost on points, 67-35.
