I'm currently 20, and I've been doing brackets for as long as I can remember--I was probably 7 or 8 when I did my first one. Some things I noticed as I filled mine out this March:

1. I've never once picked Carolina to win the title. I just can't bring myself to do it. Even in 2005, I think I had them losing in the regional final. I end up rationalizing things to myself, too: "You know, it's not that I hate them; I just don't like their chances this year."

2. I always have at least one 4 beating a 13 and at least one 5 beating a 12.

3. A good 75%-80% of the time I take the 9 over the 8.

4. I tend not to have too many 1 vs. 2 regional finals.

5. I never have more than three 1's make the Elite 8.

6. I always, always, always have at least one bracket that has Duke winning it all. I can't bring myself not to do this--it just feels wrong. As with the Carolina situation, I'm always able to rationalize this in some manner. This year, it's: "This team has enough talent to go on a hot streak and beat anyone in the nation if it can just play 40 minutes of basketball instead of 20 or 30." I'm sure I'm not the only one here who does this, either.

Any of ya'll have any weird bracket habits?
