Mayock is a tireless worker, and the Raiders need a guy who is going to come in, and get the job done. Not to say Reggie McKenzie did not work hard during his time as the Raiders general manager, but if he is going to be replaced, you want it to be with a guy who is going to work long hours, much like Gruden does.
In addition, Mayock is a former NFL player, and has been around the game forever. He knows what it takes to win at the NFL level, and while he may end up having to bounce everything off Gruden, he is also the kind of guy who is going to stand up to the $100 million coach if he feels the right decision is not being made.
As former colleague Rich Eisen tweeted out on Monday, Mayock is a classic Gruden Grinder, and the two should get along very well. They have a tall task ahead of them, and the future of the organization will depend on whether or not they can co-exist.
