A.) Offer him to Memphis for Marc Gasol
B.) Keep him. Force Kobe into retirement or him to sign elsewhere once his current contract ends and start actually building around Dwight.
B is actually my first choice, but I have a feeling they are loyal to Kobe to a fault in which case A wouldn't be a terrible option. Marc and Pau play well together and are both the kind of player that can play off Kobe well.
