"Who is rejoicing?" The ones who are rubbing it in the faces of "Dak Supporters", even the ones who can admit that he is a flawed QB. Discredit what Dak does well, get angry and resentful when a thread is made crediting Dak for what he does well or accomplished. Spend time in the thread debating on what Dak really shouldn't get credit for the good things he does manage to do.
Then it game threads. "lol, where are the Dak Supporters, can't wait to see Dak Supporters defend that one. Ha, Ha Dak Supporters take that". This type of gleeful attitude. Not being able to wait until Dak has a bad game to rub it in the faces of Dak Supporters and poke fun at Dak Supporters.
There is rejoicing going on. Those who are resentful about the Cowboys winning games with Dak and those that have resented Dak since 2016, with their "If only Romo" dreams. Are happy about today's game. Bashing Dak no matter what he says or does.
Some hate Dak more than they love the Cowboys, to the point of not being happy with wins.
