It means if you hit on thier upside you have an all star caliber player...a legit #1, #2 or #3 guy on your team....
I think both of those guys have high upside possibility....and both have very good NBA qualities about them and no real red flags, that I have been able to find...
Jones, by all accounts is a good kid, hard worker...just needs to work on not floating in games, being aggressive...That can be taught\developed IMO, heck it was taught with LA, who had similiar issues....but he has freakish wingspan apparently, great size, athleticism and skill...IMO worst case he is like a Nic Batum, solid rotation player, likely starter...best case he is a perennial all star...I would take that risk....
Rivers has an NBA skill that IMO is very important and lacking on POR, the ability to create shots, mainly for himself right now, but again as he plays with better players he will learn how to look to create for others as well....The kid oozes confidence and has a history of delivering big shots when his team needs them...he is not afraid to be that guy to take the shot when your team desperately needs it and he has the skill to make the shot...I'll be curious to see his size\measureables...but I think he is being severely underrated right now. I think he is a higher risk boom\bust type of guy, but his NBA pedigree and confidence certainly help alleviate some of that concern for me...
