Here's a bit of HS mix for Brown (skip the first minute or two)...
Markus Howard?
A sleeper pick for the Jazz might be Troy Brown from Oregon. He's 6'7", 215 lbs., with a 6'11" wingspan. He plays SF, has good athleticism and can push the ball and make plays with the pass as well as shoot from distance (36% 3-pt% on 3 atg). He has some history of playing PG in AAU, and it looks like he could put on another 10 lbs quite easily. He defends well in a wide stance and averages 1.3 steals. He also rebounds well for his size (7.6 rpg). I actually might prefer him to what I've seen of Lonnie Walker.
Simmons has a smooth-looking offensive game that reminds me a bit of D'Angelo Russell without the stellar passing. He should be able to score if he gets enough space. He's a good, but not stellar athlete.
I realise this is not far from treasonous but Rudy for the number 1 pick Ayton would be something. I still feel like an SOB for even thinking it.
