There also might be different treatment programs based on the goals... like i want to be 100% for the playoffs vs. I want to play in 1-2 weeks. I really, really, really think this has part to do with DM basically being left out of All-NBA in large part due to games missed. Maybe he wanted to get on the court sooner than later and they took a different approach... its like 32-35M difference.
The front office and player may have had competing goals and he didn't like that his voice didn't carry enough weight?
