Therein lies the problem -- if you're betting so little that it won't effect you if you win or lose, then winning doesn't have that rush.
Last night was the first time in a while I've gotten stressed out on a game. I think it's because it was one of those middle of the week games that you know if you lose you'll have to dwell on it until Saturday. Kicked ass for 3 weeks in football, then gave 70% of it back in a 2 week span. Had my max play on UAB last night, with every # I had in my ratings saying they were a better team by at least 10-12 points and *getting* +3... They went down 17-3 early due to 4 dropped passes that led to 2 missed touchdown opportunities. I was irate. Then, the 2nd quarter got rolling, the WR's learned how to catch, and UAB rolled.
It's weird how quickly you can swing from "no way this loses" to "I doubt any of these win".
