Magic get an on ball creator and facilitator in Reaves and some shooting and spacing with Knetch, plus get off KCP a year earlier with Maxi and Vincent being expirings and possibly having some veteran value come playoff time.

Lakers get 3 defensive specialists, 2 of which are veterans, to surround Luka and LeBron with. KCP would probably benefit the most from this trade and will almost certainly play better next to facilitators like Luka and LeBron and get wide open looks. Black is still full of potential and can be a secondary or tertiary ball handler in the Lakers offense. Isaac can play the dunker role on offense catching lobs while guarding the oppositions best wing. They also get into this deep draft and collect a cost controlled rookie with pick #25

I see this has mutually beneficial but am open to critiques.
