He wore the ankle braces, compression socks, knee braces, and claimed it was to prolong his career and prevent injury, and it didn't do him any good.
I think he would have been better off just wearing knee braces.
The problem with ankle braces is that every time you tweak your ankle, the generated force does not be stopped in your ankle but instead gets transfered into your knees. Of course there it can make much more damage.
I don't wanna know how many little tweaks he had that went right into his knees in the beginning of his career that summed up to the ACL.
Couple of torn tendons like Steph Curry had would have been a blessing compared to his devastating knee injuries.
I'm not saying that's the reason why he got injured but I believe it's a part of it. Pairing it with his bad landing technique (where he prolly tweaked his ankles a lot) did the rest.
On top of that it's really a shame that professional athlete coaches did not see and adress that topic in the beginning...
