I say this not as an attempt to smack down your post, but because your post gives me the opportunity to have a mini-rant on something I've been thinking about posting, so please don't take offense. Here goes:
Since when is having an advantage at home something for the league to prevent? Why didn't the league build variable fan noise into the system this year, instead of leveling off a field that's never been level? They let the architecture in Seattle happen in such a way that it increases the noise level and makes it the biggest HFA in the league. The league put a team in Denver, where the altitude gives Denver a completely unfair advantage. Hot area teams have advantages when it's hot and cold area teams have advantages when it's cold. K.C. has the loudest stadium/fan combo in the league, but that's gone now. Dome v. open air, various types of turf, east coast v. west coast travel, etc... And some teams draw like **** compared to others, or have smaller stadiums.
All this is built into the cake and accepted, but people are worried about unfair advantages all of the sudden?
