Interesting to hear the difference in noise levels and overall Detroit fan attendance since the Thanksgiving game just 2 years ago.
I was at that game - was my first visit to Detroit. It was probably about 25-30% Bills fans that day, and we were loud and proud
The sense from talking to Lions fans then was that they were hopeful about the future, but still hedging their bets
I'm sure that Thanksgiving had a lot to do with the fan mix - since Detroit hosts every year, it's not really that unique or special for them as it is for fans of the opposing team.
