Though I like Mitc Robinson, Zhaire and Robert Williams, I don't think any of them will be there for the Spurs.
But another guy I am interested in is Red Mamba Jr., Kevin Huerter
He's not popping on a lot of mocks yet, but I expect that to change with the combine.
Doesn't turn 20 until August, good wing size at 6-7, should measure with serviceable length, and just a premiere shooter of the three ball with NBA range and quick release. Also has solid playmaking for his position, nice touch, plays tough, and isn't a total cone on defense like a Musa.
