Spencer is really good and going to be huge, but I wouldn't really classify him as someone who's gonna get his own shot. Last year 61% of his shots were assisted. As a reference, Cole was at 35% of his shots being assisted his senior year.
Martin isn't a bad comp, his numbers were pretty similar to how Spencer was used last year, 55% overall and majority of his 3's coming off assists. Just not sure I'd really classify those guys as players who could get their own shot. I think of Kemba or Shabazz that at the end of the game you just give them the ball and clear out
