Avery Johnson, Deron Williams and the Nets were just .500 when Johnson was fired as head coach.A promising November gave way to a disastrous December for the Brooklyn Nets, as not only did the team go 3-10, but its three wins all came against teams with losing records. The net result was Avery Johnson losing his job, but the underlying statistical reasons for the Nets disappointing start are many and encompass all facets of the game -- offense, defense and personnel.
Nets This Season
The recent narrative for the Nets has been a lack of offensive execution, as both Deron Williams and Gerald Wallace have voiced concerns with the offense. The team does rank second-to-last in the NBA in pace but its true shooting percentage stayed consistent -- 52.5 percent in November, 52.6 percent in December.
The biggest change has come on the defensive end -- the team was ninth in opponents points per 100 possessions in November (100.0) and 28th in December (108.6).
The offense isn’t completely off the hook, though. Under Johnson, the Nets experienced the biggest drop-off in offensive efficiency, field goal percentage and rebound percentage between the first and second half of any team in the NBA this season. They've lost a league-leading six games this season in which they led by at least 13 points.
Nets By Half This Season
But the real issue with this team might not be coaching or offensive philosophy, but rather the personnel on the court. The Nets invested heavily in the Williams-Joe Johnson-Brook Lopez-Wallace core, and it simply has not lived up to its billing this season.
Williams, the franchise cornerstone, is putting up his lowest Player Efficiency Rating (17.1) and lowest assist-per-40-minutes marks (8.7) since his rookie season of 2005-06, and his field goal percentage (39.8) would be the lowest of his career.
Of the 151 players who are averaging at least 25 minutes per game this season, Williams (52nd), Lopez (74th), Johnson (83rd) and Wallace (87th) all rank outside the top 50 in Win Shares. Lopez has missed seven of the team’s 28 games, including six in December during which the Nets went 1-5. Meanwhile, Wallace has scored in single digits more times (10) than he’s scored 20 or more (2).
True Shooting Percentage
Is it possible this isn’t just a bad system fit or small sample size, but rather players in decline? Joe Johnson’s current PER of 13.6 is nearly five points lower than his mark last season and would be his lowest since 2002-03. Wallace’s PER is on a much more sustained nosedive, going from 18.6 to 18.3 to 16.2 to 15.9 to 14.6 since the 2008-09 season.
But perhaps most alarming of all is the multi-season shooting decline from Williams, who has seen his true shooting percentage drop from 59.5 in 2007-08 – which ranked tied for 29th in the NBA that season – to 51.6 this season, good for T-188th.
