As a Jefferson grad, I watched a few games last year to see what he was about. He's not at the level of like a Tyus or Suggs was their freshman year, but few are. He ran the offense well, was disruptive on defense and had enough creation ability to get 8-10 pts a game.
Jefferson rarely plays freshman on varsity, the only ones I can remember in the past 20 years are Cole Aldrich, Moses Alipate, and Marcus Alipate. All D1 level athletes, only reason Marcus went to St. Thomas was he topped out around 5'10".
