Having spent my career around leg injuries, I really don't think the overall response is warranted.
These kinds of muscle strains are touchy, and they can be long-term - especially if the patient isn't patient - hahaha - with their recovery. I can certainly see the potential struggle with keeping Garnett in a recovery mode - much easier than I can see the Celtics front office engaging in a disinformation campaign that has very little, if any, potential to benefit them.
Much ado about nothing, if you ask me.
