If you keep Zo, you are investing heavy money into a core I just personally don't leave in that much from a mental makeup standpoint and skill set. We all know Zo is improving, but even at his peak, I just don't think with the assembled core it will ever generate us as a top 4 team in the West.
Alot of fans are not looking at the long term implications of the core when committing, and honestly I just don't want us to be mediocre, because it will be AD all over again.
