Why keep Weaver if you are hiring someone else and giving him Weavers power?
A president can make sense. Tom Wilson was the president for years. But he ran the business side, and while technically Dumars reported to Wilson, Dumars ran the basketball side.
But JEIII made it sound like the new person would be running the basketball side. At that point I don't see why Weaver would be retained. Redundant layers of management is the calling card of a poorly run organization, so par for the course I guess.
