Where did I say Dak's family can't defend him?
Second, maybe you're responding to some many people that you're conflating arguments.
I've already acknowledged there is actual "cyber bullying" taking place. My point is that Dak and his family must assume that because he's performing his job in public he's going to be criticized.
Furthermore, we need a bit of clarification of interpretation. If someone says "Dak sucks" what do you think they're talking about? If they're talking about actual sucking because Dak has performed something on them, well, that's out of bounds. If in the context of football, that IS job criticism. They're basically saying he's no good at his job.
But that as it may, Dak understands what comes with being the Cowboys quarterback and what occurs when he under performs. He can choose to handle it how he sees fit. But that doesn't mean he's going to change anything while he's the quarterback of the most popular franchise in the world.
Shrug.
