Gurley is being transparent. He's cracking the ol. Much like him standing around being a bad teammate starring down Havenstein and the shaking his head at him for everyone to see. He's being a baby on the field and showing them up.
If I was Havs I would be having words. If and of the rbs I played with did that I'd be putting challenging them behind closed doors. I was a defensive player and hated that crap. It's his job to not let one man tackle him. At some point it's up to him to be a man and throw a defender on the ground. He has lost his will and it's sickening.
