Preseason rankings are a bit like predicting the weather—someone might be able to make an educated guess, but it's still a guess.
Some preseason rankings pan out. All four of the 2009-10 Final Four teams were in the ESPN/USA Today preseason top 10.
Some highly ranked teams in the preseason flounder. North Carolina was a top 10 team before the start of last season. Connecticut and Michigan weren't far behind.
And then there are the teams that are overlooked as contenders.
Every season, there are several teams that aren't included in Final Four discussions at the start of the season even though they have all the pieces to make a serious run at a title. They may be ranked, but they aren't considered to be legitimate contenders. Butler and Duke certainly fell into that category last year. Heck, Butler was a No. 5 seed in the NCAA tournament despite losing only four games in a season where they began in the top 10.
Who are the underrated teams this season? We've got five teams to keep an eye on.
