The Swift thing is kind of human nature I think. A large percentage of football fans love the game. So they see the extra-curricular type stuff as a distraction from the "seriousness" of the game. It's like the infiltration of a bunch of people who "don't know", or "don't understand", or "don't appreciate" the game. That's what the mindset is when the broadcast cuts to her. Hockey purists HATED the glowing puck thing when Fox (?) tried that for a while. Taylor Swift is sort of a glowing puck addition to the broadcast, that a lot of people who like / love the GAME see more as some schmuck in NY who doesn't give one tiny crap about the game yelling at the production team to get more Taylor shots so the extra 2 million teens watching don't tune out.
Sorta like kids with their musical tastes... they want to champion how great it is, while also shunning anyone who might listen but doesn't look a certain way, and then complain that their music doesn't get the respect it deserves.
For the record, it bugs me that they feel the need to show her reaction specifically to things. As somewhat of a baseball "purist", I hate the HR or nothing nature of the game now, and the over the top HR celebrations that come with it. Hate it. Human nature...
So the glowing puck is gone, but ABC does this thing during power plays now where whoever has the puck it shows their name next to them like a video game. Considering all the passing that occurs, it gets really annoying and distracting.
