Neyland Stadium is Not #1
Neyland stadium isn't the best place to watch a football game. The last time I checked, Ole Miss had the best gameday experience, LSU had the toughest place to play in, and Alabama has more tradition, and championships than Tennessee, not to even factor in that BAMA fans are much more fanatics about football than Tennessee fans.
Florida had a much more intimidating stadium, and Neyland stadium has 14" wide seats compared to 18-23" for all other stadiums. The paint is chipped, and looks terrible, and Arkansas probably has the prettiest of them all.
If your rankings go by tradition, fan base, etc, then you're way off. All Neyland has is about 10,000 more CROWDED seats. BAMA will surpass that 102,000 within 2 years, and Auburn is a much more prettier site venue than Knoxville.
