Let's once again get the obvious out of the way. There is just no reason to avoid him against the Dallas Cowboys.
Rob Gronkowski has over 100 receiving yards in two of his three games so far this season, and against the Steelers, he only missed that mark by six yards. He has scored in every game he has played in, and he is going to score again this week.
The Cowboys injury-plagued defense simply does not have the man power to cover "The Gronk." He should go over 100 yards and score at least one touchdown. You're obviously starting him in your seasonal lineups, and if you play in daily leagues plug him in as well. Sit back, relax, and enjoy the show.
