1. Derek Carr's inconsistency
When you look at a quarterback like Derek Carr, you see a man that is very consistent at his job. The problem, however, is the fact that he needs to be more than just consistent to make the playoffs.
Think about it! Carr might be a good quarterback. Heck, he might even be an upper-tier quarterback in some eyes, but he is not someone that is going to take the Las Vegas Raiders all the way.
