I'd put Harward as an average athlete. He's more athletic than Lee or Knell. And he is 6'11 with a pretty solid frame, and moves pretty well for a pure 5.
Erickson is probably a better ball handler than Harding or Johnson.
I have different opinions on who I think will be the best scorers. But everyone will differ on that. I'd put Harward, Baxter, George high on that list.
