Something like 4/$140M would be a steal on Ivey I think. Unless you don't see him improving next year. But he has improved all 3 seasons, no reason to believe that will stop now. He is going to be a guy that scores 20+ ppg shoots 40% from three and can get to the rim with ease. That gets him the max after next season no problem.
Of course, if I'm Ivey I never sign for anything less than the max. Security be damned.
