Suns are in desperate need of a PG and even if you say Beal is great its just that they lost too much for that to happen with his injury prone history and they as well as a long wing that can defend and score, Hayward is a perfect dude for them who can defend the team forwards or big guards while being 3rd best player for suns. They would get 2 guys that can defend their respective positions and that'll be more fierce with shot making of book & kd. Spacing will be better too.

Hornets are in a stage where they wouldn't want to be bad every season and Beal with lamelo could be a good backcourt for sometime with improving Miller & PJ/Bridges & Williams. They can talk themselves into this trade but very few chance of this to happen as Suns gave way too much for Beal.
