Don't sleep on Zion. The injury set him back last year, I think he will be much improved.
IMO what will be interesting is Solo and Jacobson if it come down to who starts vs who comes off the bench.. 2 year starter vs 1 year starter. Solo turned around the team his freshman year, is a better defender against big 12 level post players and lost his spot due to injury. Jacobson had a great year last year, is better scorer and rebounded.
Yeah, I think Zion has a chance if he puts in the work. He had to probably adjust the most of the freshman to college because he was used to being a post in HS.
