I rate both Humphries and White, great kids, now young men who are still developing and both will potentially have big futures ahead of them because they have the ambition to match their skill, ability, talent and attributes.
Isaac may have tried to enter the NBA draft too early, you could blame the Kentucky staff who advised him, or someone else giving him misinformation, you could look at many things and point at them, however he has now taken a different pathway and is still a prospect.
Both of them will have a bright future, too many people get hung up on what 'making it' is and don't get the big picture, settle people!
