I recently wrote about how players have performed coming back from Achilles injuries, noting that Rudy Gay of the San Antonio Spurs is on track to become only the fourth player out of 18 comebacks since 1990 to meet or exceed his pre-injury projection the following season.
Gay's example provides hope but, on average, players coming back from Achilles injuries see their production decline by about 8 percent compared to what we would project based on their past performance and age. The good news is Cousins is so dominant he can afford to decline by 8 percent and remain a very good player. Nonetheless, it's possible that this injury will rob us of the peak Boogie we saw this season in New Orleans. And that has huge ramifications for both him and the Pelicans.
I found this to be interesting that they have quantified the production decline following an ACL tear. Would an 8% better Brandon Rush be a started in the NBA? Or 16% better following his 2nd ACL tear in 2012?
