One kind of odd thing specific to TN fans is their schedule. Other than the year in which they won the MNC, here's how almost every year has played out.
Preseason - aggy level hype; up the roller coaster
Week 3 - Lose to Florida. Fans start to have 2nd thoughts about their expectations.
Weeks 4-7 - Lose to Bama, Georgia. Fire the coach!
Weeks8+ - End the year with 4 patsies and usually a pretty easy bowl game. Here's there last 9 bowl opponents: Iowa, (10-3) Clemson, Purdue, Indiana, Nebraska, Northwestern, Iowa, North Carolina, Virginia Tech.
So they go on the exact same roller coaster every year. We're good, wait a minute, we suck, nope, we're good again and end on a 4 or 5 game winning streak. That has to mess with ones psyche over time. They spend 49 of 52 weeks each year pretty content with what's going on. They very rarely end the season on a bad note, so they're hyped from about Nov 1st until late Sept when they play Florida.
