Mistake to compare him to Lebron. He doesn't play the same way. Lebron is much more of a facilitator, more ball dominant. Really a big PG.
Jackson is more of a jack of all trades, let's the game come to him, makes a good basketball decision almost every moment he's on the floor. He moves the ball, he drives when there is room, good handle, he takes the open shot, he boxes out for rebounds, he defends multiple positions.
His movement on the court is not at all like Lebron. He glides like Dr. J or Clyde Drexler. Old school, in a good way. Fundamentally one of the soundest college freshmen I have seen in quite some time.
