Before his first Opening Day start at QB, Mahomes already had a full season of tutelage under his belt at the side of Andy freakin’ Reid. He learned how to handle being in the NFL for a year before he had the pressure of a mid-season playoff race to deal with. He walked into a playoff caliber offense with established talent and a system that everyone already knew like the back of their hand. There is no comparison between what CJ is doing now vs. what Mahomes did in his first full season as QB.
What about referees influencing second half betting lines?
