Haha, I'd actually say he provides a contrary example! From everything I've read, Mark is a much better person than his father. Whereas Trump gambled big with his father's money and nearly squandered it all and then turned himself into a market predator with a legendarily lavish and wasteful lifestyle, Mark Davis is living a relatively modest life and is a much more humble and effective owner than his father. Al micromanaged the Raiders into shit with his awful hubris, whereas Mark has stayed out of personnel decisions for the most part.
