The subtext for people who are mad at Keshon is that he is healthy enough to play and is choosing not to for reasons not explained.
I've watched him the past two months and i don't think he's healthy enough to contribute, so for me it's not a huge thing. I just don't know what people have been watching or seeing to think he's ready to go, but won't.
As far as Petersen and Williams making a thing about KG being evasive to questioning about his health in recent weeks as a major bullet point to their insinuation he's opted out, keep in mind that evasiveness may have come from his own coaches who didn't want him speaking openly before the seeding for the tournament was announced. They seem to want to give TJ credit for this, without acknowledging that framing Keshon's responses to the press when asked about it would be job #1 there.
Keshon never did anything publicly for people to claim he's a quitter in his time here. Actually plenty to the opposite. If people have evidence he's ready to play but refuses to, it's time to show that, or forget about it.
