I have his injury. It was not logical to skip the surgery. That meant he was counting on his hip to correct itself. Turns out 9 days into his season (or whatever) he wasn't above doctor's orders. He was above letting his agent negotiate for him in a professional setting and it effected his earnings. His hubris is stupid but his situation is tragic. If he doesn't ball in Denver we're looking at China or Dancing With The Stars.
Sorry to hear that you have his injury. From all the research I've read, though, athletes don't always benefit from the surgery, effectiveness often depends on severity, and it's common for recovery to take several years at the pro-level. At 30 y/o and heavily reliant on athleticism, allowing it to heal on its own was probably the ideal option and clearly within the scope of possibility if doctors believed the same. Unless, of course, the Celtics trainers and/or brass were biased in their interpretation, which is consistent with his saying the organization could've handled it better.
Regarding his hubris and stupidity, that's unfair. You can argue whether his intentions were self-serving (e.g., paycheck), but regardless, he sacrificed his own well-being for the organization at several times during the season. Moreover, he indicates in this interview that his decision to play was affected by his sister's passing - basketball served as a coping mechanism, clearly a distraction from the pain. Minimizing that, cracking on IT, and not appreciating the fact that he 1) made us relevant during gap years, and 2) was the most entertaining show since Broadway on Ice is tough. Shame on you, Mr. Pemulis.
