I did today watching the highlights..
They (cbs, all sports channels) have the visuals and sound mixed live creatively for broadcast. It's subtle but they are very clever the mixers on the live sports feed.. When the Bills scored and you see Allens family celebrating.. they 'drop the sound out' so that the mix of a small section of away supporters in the crowd comes through more. (Might literally be Allens family). It changes from the whole crowd sound on the main wide shots, so you can hear this small section and it really highlights the underdog, away thing..
They mix throughout the game between the loud home supporters and the Bills audio support they choose to. If you notice on the throw to Davis in the EZ they cut to the same audio feed as the Allens Family image (you can hear a few more female voices cheering, just coming through) which makes it feel very emotional when they show Allens family. It's done I think to make the emotional link between his family, mom there rooting for him.
It's all done to make you feel like nothing is done if you know what I mean - They are very good at creating an underdog vs giant narrative with it and it adds to the drama.
They also mix to the players when there's a TD and when Davis scored the last touchdown you hear Diggs saying 'shut the f'*** up!!!! '
