I've said it many times and will keep saying it. Running qbs never work. They are good for a short while and that's it. Lamar hit his ceiling last year. Unless he does something drastic like learn to become a pocket passer (kinda like what Allen did with palmer) the Ravens will continue to get worse. I could see them being a 7 win team next year. Running qbs always get figured out.
Another factor is the fact that the more people in a place the more the sound is absorbed. So while 70k people will still be louder, 7k people can still make a heck of alot of noise with less sound being absorbed by 63k less bodies.
My 40th birthday was Jan 7th this year. It's pretty depressing turning 40, but this year has been pretty awesome with the bills winning in the playoffs
