I know it's weird to see Randle as a deal breaker... but (healthy) Randle and Smart are about even in trade value in my opinion. If you're the Lakers, why would you bother to include Randle? Nobody is outbidding you if you give up the #2 pick.
Lakers should stand firm on refusing to give up Randle. Kings are playing hardball... they'll cave. You got this in the bag, LA. Just offer the #2 and nothing else. Trust me on this. I know what I'm talking about. When Vlade calls and says, "Seriously... include Randle or I'm trading Cousins to Boston", just call his bluff. There's no way he passes up the opportunity to get the #2 pick. You win, Lakers. You win.
