I've never seen a single Cowboy fan here on CZ hate on Dak. I have seen some be critical of his play. There's a huge difference. Stop labeling criticism as "hate." The two are very different things. Dak made awful decisions that cost his team the game the last two times he's played the 49ers in the playoffs (not that he was the only one who played poorly). Anyone who is saying, "Well, I love him, so I'm not going to criticize anything he did" is being ridiculous.

So, to answer your question, no, it won't silence any haters because there isn't anyone here who hates him. Those who have criticized his poor play will be like, "This is awesome! He's playing great now."
