Memphis has suffered more missed games due to injury than the Jazz, and they have a worse record than us.
The Clippers have suffered nearly the same number of missed games due to injury as the Jazz, yet they also have a better record vs. playoff teams than us.
As far as the quality of the players that are lost via injury is concerned, from a VORP (value over replacement player) metric, the Clippers have suffered more than anyone as their missed games involve superstar level players.
How is it that these teams can withstand injuries and still have a winning record vs. Playoff teams, but we need to rely on the injury excuse to explain our poor record vs. Playoff teams?
