The Washington Wizards' fortunes have fluctuated over the last decade. They went from being a .500 NBA team in 2006 to one of the worst teams in the league in 2009. Since then, they're improved and again finished this season at .500. By using an advance metric called wins above replacement player (WARP), it's possible to see which players were most responsible for their success, and which ones dragged the team down. Here are six things we learned by crunching the numbers.
Generally, Wizards players who contributed more to the team's success got more playing time. For example, Gilbert Arenas played an average of 42 minutes per game in 2006 -- the most of any Wizard over the last decade. His WARP that season was 17.28, meaning his performance accounted for 17 more wins than if he had been replaced by an average player. But there were a few outliers - players who were a significant part of the team's rotation but actually cost the team wins instead of adding them. In 2008, Nick Young, who is known as a strictly offensive player and a defensive liability, played 22.4 minutes per game and had a WARP of -3.51.
After the Wizards traded Arenas in 2010, the team drafted John Wall. A natural playmaker, Wall showed solid improvement in the years following his rookie season, becoming a better shooter and passer. But his WARP has hovered around 10 for the last three seasons, and has yet to reach Arenas' peak WARP, 17.28 in 2006.
The Wizards' success over the past decade has been largely dependent on the play of Arenas and Wall, the team's biggest stars. From 2005 to 2007, when Arenas was at his best (and with some help from one or two main supporting players), Washington finished above .500 and was a playoff team. But when Arenas went downhill, so did the Wizards. They became one of the worst teams in the league. As John Wall's career progressed, they got better again, reaching the playoffs in 2014 and 2015 after a five-year drought. Now that Wall's progression seems to have slowed, so has the team's. They missed the playoffs this past season.
In 2006, the combined WARP of every Wizards player was 32.67. Arenas' WARP that season -- 17.28 -- accounted for more than half of the team's total.
In 2015, the combined WARP of every Wizards player was 27.81. Wall's WARP that season -- 10.53 -- accounted for about a third of the team's total.
Beal was the third pick of the 2012 NBA draft, and Porter was the third pick of the 2013 draft. Beal's numbers aren't bad, but this past season, Porter was significantly more valuable than Beal. Beal's WARP has been up and down since he came into the league -- and this year was a down year. Porter's, however, has shot straight up.
