Its not my style to judge injuries, pain threshold, etc. Most athletes obviously want to play more than any fan could ever want them to, so I viewed this like, even if this was a mental block, anxiety type thing, fair enough.
Where I draw the line, is with him apparently showing no commitment to team off the court and hiding publicly, forcing them to constantly have to answer for him. You'd think when you're already sitting out despite being medically cleared, you'd go out of your way to be at least present as much as possible to show that you're invested.
The fact that he doesn't feel the need to do so with, in some cases, people he's played with or for, in excess of 6 seasons and practically won 2 championships with, makes it especially bizarre.
