What will this crowd sound like?

MINNEAPOLIS -- I'm interested to see if the Metrodome's crowd dynamic will change much for Sunday's game against Philadelphia. You have to assume there are going to be a lot of new people in attendance given the reported levels of season-ticket holders who picked up their option to purchase tickets for this game.

At the beginning of the week, only 55 percent of the team's ticket base had bought tickets. I'm sure that number increased over time, but you would have to guess that at least 25 percent of the fans Sunday afternoon will be people who don't normally attend games.

Will that make the Metrodome louder? Quieter? How many of the newcomers will be Eagles fans?

It's worth nothing that the Eagles aren't easily affected by crowd noise. Their 13 false-start penalties were the third-fewest in the league. For comparison, Minnesota right tackle Ryan Cook committed six false starts on his own this season.
