He's averaging 11 and 4 as the third option at Kentucky (behind two freshmen, incidentally). Last night UK got drilled by Georgia and he had 5 and 1. Robinson is not an NBA kid, let alone a lottery pick. I expect him to make a G-league roster at best. And he's as good as he's going to get.
Catchings and Demin have great upside, I think. I think. Demin can really pass the ball, and probably he'll be a decent shooter. His handle is a problem, as it is for all guys his height, if he's going to legit play point in the League. Catchings is long and has good instincts, but he's got to be a better shooter if he's going to play pro ball. His defense is poor, his court vision is bad, he doesn't rotate or stay on his feet on closeouts, and when he isn't scoring he's essentially invisible on offense (though there have been moments of real hustle on the offensive glass, which might be a sign of good things to come).
