Many of us talked about it before Zion even committed to duke, the kid is 6' 4" and in shape carries 285lbs, his upper body mass is crazy and his vertical that carries that weight is amazing. To carry that kind of weight, to quickly explode up constantly thru a game in college or before that was 1 thing but doing so over the course of a very long NBA season is a whole different proposition. Physically, there is just no way those legs take that kind of pounding long term and not begin to break down.
We saw it at duke, happened against us, knee could not take the pounding, we saw it in his first G-league game, knee balked at the pounding, and now we have seen it in what, his second pre-season game? How extensive is the damage already done? That quick, extreme explosion vertically up with raw power is his calling card, it defines his game, without that where is his game special? He is not a great jump shooter, he is not a great ball handle, he certainly is not a great assist maker?
