Just four teams left in the NFL and two big games this weekend. It will be interesting to see what happens crowd-wise in both games. A sports writer in Denver appealed to fans before their last game to get loud again like they used to be.That wasn't a problem in Seattle. Fans got so wound up during the win over New Orleans that they generated a jiggle in seismographs. The last series of playoff games were fun to watch and this weekends shouldn't be any different.
