I remember watching a game on live TV between the Soviets and the US, a year or so after the posted video. Sabas (I believe 19 or 20 at the time) dominated much better competition (I think Ewing and/or Sampson was on the US squad, along with some other pretty good bigs). Sabas just overpowered the US centers. I remember one play where he backed down his defender and looked like he was going to shoot a hook shot, only when the ball got to the top of his reach, he didn't let go, he continued to follow through with a massive sweeping dunk right over his defender. He looked like a man among boys, and I remember thinking at the time, "If this is the kind of player the Soviets are producing, the US will never will another Olympic gold medal". He was that dominant.
