#5 Not getting rid of Jon Gruden
Let's be honest here. Jon Gruden is not working out as head coach of the Las Vegas Raiders, and everyone knows it. In fact, besides Derek Carr versus Marcus Mariota, whether or not to fire Gruden was the talk of the town. Now, many defended Gruden due to how new the defense he had put together was, but others saw his offseason acquisitions as dead weight on their best day. In all honesty, the defense was one of the worst parts of the team, and Gruden is a big part of that.
He has already proven on multiple occasions that he can't call a winning play to save his life and ends up getting snuffed out in close games. Furthermore, he gets completely blown out by what should be inferior teams. Think about it! His record speaks for itself over the past three years, and it isn't something to be proud of.
