Just using without shoes heights (Tyus is 6'0.25") as a comparison, you won't find a successful NBA point guard under 6'1' without shoes who tested as poor athletically as Tyus did. Slower than many power forwards and has the lateral quickness of a center? Career backup or bust. And the Rockets don't need a point guard who doesn't play defense. In the playoffs all five positions have to defend, especially your guards if your facing the taller Stephen Curry and Klay Thompson.
