I had the good fortune of watching the game being called by Bill Jones and Isaiah Stanback. A good friend, who is also a Cowboys fan, watched the NFL Network broadcast with the Seattle broadcast team. He heard it too.
They can and did make the remark, but they could have kept to criticizing how the Seahawks second, third, and fourth string players were performing. I mean, that is THEIR team. Whether anyone would have appreciated it or not, Jones and Stanback could have made the observation instead. It would have made more sense for them to fill their COWBOYS airtime with a Dallas-related comment.
I wish my curiosity were stronger on the topic. If it were, I would scope out their call of the Titans game. Surely, they can quip about something related to Tennessee's postseason difficulties too. Right?
