Not a terrible idea. Lonzo can’t defend but neither can kemba. but lonzo has length and tools to be taught to be at least passable hopefully. At worst, Smart and brown can hide his perimeter D. But his play making ability is worth it
The only issue with lonzo is his family. Dad is a nut case but he has calmed down in recent years. The other issue no one talks about is that I think lonzo (or his dads wish) eventually will want to play with his brother . But that is likely later in his career but you never know
