Matthews' ratings drop makes me question whether scouts are as knee-jerk as some of the fans on this board. Or whether there was an element of "oh, Calipari might have made a recruiting mistake, so let's highlight it" to the drop.
Matthews went into last spring rated in the 10-20 range. Maybe that was too high, and I know that a lot of it was based on physical potential- he was never a great offensive player, but he has the size and athletic ability you see in an NBA 2 guard. Matthews did not have a good spring and summer. His AAU team wasn't as good as the year before, because they lost Tyler Ulis and Paul White (Georgetown), and Matthews' shooting hadn't seemed to improve. He was also hurt for at least part of the time. So scouts dropped him 30-40 spots.
That seemed excessive. It seemed excessive then, and it definitely seems excessive now. Worst case, I think he has the type of talent that DeAndre Liggins or Darius Miller had (even if he ends up a different type of player than either). Best case, he can be every bit as good as Archie Goodwin, but with a better basketball IQ.
