Same injury started Cousin's slide as KD is trying to come back from....
Actually you could go back farther with KD. Off the top of my head, in the last few years he’s had a right foot fracture (Jones fracture), right knee hyperextension, right calf strain, and right Achilles’ rupture.
I think that you’re suggesting that Durant might possibly not ever be the player he once was. I think there’s a good chance that that’s right.
As for Cousins, the Achilles’ rupture, quad tear, and ACL rupture were all on the left side. I bet he’s done, frankly.
