He is as big a homer as any announcer, but he could not believe KD tried to play.
He's fucking full of shit. He has no idea if the Warriors "pressured him" to play against his will. Given that KD is arguably the most powerful person in the league right now, and was Instagramming out his love to his teammates right after the injury, the reasonable assumption is that they did not.
Grade 2 calf strains happen all the time in the NBA. Typical recovery time is 4-6 weeks; and KD was right at 5 weeks when he returned. They (= KD and the med staff) may have been aggressive with the timeline, and may have assumed a mild risk of re-straining the same calf muscle, but did anyone think there was a real risk of a ruptured Achilles? I know they're in the same area, but is there precedent for a player returning from a strained calf and immediately tearing his Achilles? I dunno, I'd allow a strong possibility that we're dealing with a pretty freak injury that could have happened at any time, including during rehab.
In any case, get well soon, KD. As others have noted here, however severe the MRI reveals it to be, he's gonna get multi-year max offers from multiple teams, including the Warriors. We're not talking about Isaiah Thomas or DeMarcus Cousins here, with all due respect to those guys. You take a bigger risk for the late prime years of a guy who when healthy is the best player in the world. In the Warriors' case, there's not even a risk in terms of opportunity cost, since they can't replace him if he signs elsewhere. Yeah, there's luxury taxes to consider, but those are less painful when you're sitting on a $4B asset that you paid $400M for ten years ago, and are about to open a new SF Cash Cow Palace that you financed on other people's dimes with corporate naming rights.
Also, knock on wood furiously, but KD's game is based so much on his ridiculous combo of length and skill (as opposed to speed or explosive athleticism) that I'd bet he'll get closer to 100% when he returns than a lot of guys.
