Here is a list of some of the healthiest teams as measured by man games lost to injury this season: OKC, Raptors, Spurs, Pacers, and the Trailblazers. These 5 teams are all top 6 in losing the least amount of man games this season. Cleveland is the outlier here in the top 6.
And here is a list of some of the unhealthiest teams as measured by man games lost: 76ers, Bucks, Lakers, Nets, and the Wizards. The Warriors and the Clippers are the outliers here as to their performance.
The Wizards are ranked 7th in most man games lost to injury. We have lost 87 games this season, but we have improved from 104 games lost to injury at this same time last season. The Timberwolves have also improved as well from losing 113 games to 78 this season. Both teams are also playing better and have risen in their respective standings.
The Wizards have lost games from Harrington, Porter, Singleton, Beal, Rice Jr, Nene, Ariza, Seraphin and Webster. Of course we also lost Okafor for the season and traded him for Gortat, but that doesn't count in these rankings. .
Over a two year period - the Wizards would be ranked the third most injured team in the NBA with the 76ers and Clippers losing even more man games in the period measured. We are tied with the Timberwolves for the third spot.
