If I was a betting man, I'd say Smart. Mudiay is just such a high risk/high reward prospect that it's hard to have too much confidence in him. Mudiay could be GREAT, but he could easily be the next Johnny Flynn. Smart could be the next Wade, he could be a defensive role player. I'd say Mudiay's ceiling's a bit higher, but Smart is more likely to reach his ceiling. D'Angelo Russell might be a different story though...
