Offensively, I think Hood can become as good or better than Hayward. Hood is extremely streaky, there's no in-between with him...but people forget, so was Hayward in the first 3-4 seasons of his career. The problem with Hood is, if his shot isn't falling, he doesn't do anything else to positively affect the game. That is where Hayward is a lot better than Hood.
Hood needs to improve on his consistency, and become a better defender, passer and rebounder. His ball handling is pretty good just like Hayward though...
