In no particular order, I like Smart, Young, Rozier and Olynyk.
Smart - has the mentality and overall game to get there.
Young - If it all clicks within another 1-2 years, I could see him becoming a pretty lethal scorer - odds are long though here.
Rozier - that kid looks like he has the tools to be physically dominant on both ends of the floor, so i he works on his handle and shooting, he coudl have a pretty high ceiling.
Olynyk - seems so passive, but like Young, if it all Clicks this year or next, he continues working on his body and through continued playing time and experience his confidence on a night to night basis levels out, he has the tools to really impact a game in many ways.
But the guy to me that really stands out as having star potential is RJ Hunter.
* He's really long and has sneaky athleticism
* This will be good for him on D and help make up for his current lack of strength
* You can see he is already working on his strength
* He's has no conscience as a shooter, but he doesn't take many bad shots either - really important if you want to be a dominant scorer.
* He combines all this with some very good ball handling and passing skills.
* Looks like he's got a real motor - never stops moving.
I also think Mickey could turn into a workhorse type PF along the lines of a Horace Grant. Not spectacular but a steady 15 & 8 with very good defense. I'm not saying all star here - but long term starter potential.
