Irving looks like the best pure PG prospect since Paul and Williams. While he's not as athletic as guys like Rose, Westbrook and Wall, I think he'll be better at managing a team. I buy the comparisons to CP3.
Perry Jones is a straight tease at this moment. Great talent, body, but questionable motor. Doesn't have that killer instinct.
Probably the most intriguing prospect is big man Jonas Valancuinas. Some of you may be thinking, "not another soft Euro". From all accounts, this guy is far from soft. He has a huge wingspan, good motor, shoots around 90% from the line, and best of all, plays around the rim.
