How today Rivera's fault?
He's the head football coach, that's why. This team is HIS responsibility. He's the be all, end all of every single decision that happens on the field.
Bad playcalling? His fault. Dropped passes? His fault. Penalties? His fault. Loss in a close game? His fault. This team is his gain and his loss.
He's the boss. It's like ANYTHING else. If something is broken, it's his job to fix it himself or locate a person or course of action to fix it. That's the job description of the boss.
It's his staff, his team, his players, everything that happens between the lines belongs to him.
If someone goes on the field with their shoes untied, it's his fault.
He isn't doing his job. This team is undisciplined, and it's his fault. This team also doesn't execute, and it's his fault.
He needs to go, and he needs to go now. I've been in his corner, but HE NEEDS TO GO.
