So what do the Jazz want to see out of Neto? He's proven he can make an impact in short spurts, like he did against the Lakers. But it's harder to be effective with more minutes. And also, Neto won't be playing against Jabari Brown or Lou Williams - aka bench guys. He'll be playing against Brandon Knight and Eric Bledsoe - aka top end starting guards in the NBA. So the Jazz are interested to see what kind of adjustment Neto can make against a jump in competition.
Also, Neto will be playing with starters tonight, which is also an adjustment.
