I disagree. I interpreted this as opposite of your take (that he's been managed very well).
The main details are that (a) this was never a surgical option, (b) the coaches have managed it perfectly, and (c) because it's been managed well, Gary played in a bunch of games early and will still play in a bunch of games late.
That's all directly from Rashan's mom: That he had a non-surgical (pain only) injury and was able to play at a high level despite that ... until he suffered an additional injury and immediately took time off ... with more than enough time to return at full strength this season.
