My choices aren't exactly based on the way each team has been playing all season or how strong their offense or defense is. Rather it's me looking at the seeding and figuring out who I think will advance. Or sometimes my decision is completely arbitrary and I choose based on whether or not I like their name or if I have a good feeling about a certain team. I know, I know, it's ridiculous, but it generally works for me.
I don't like to bet on the games because it takes the fun out of it for me, but Fox Sports had the right idea when they made the $1,000,000 Bracket Challenge. If you're like me and didn't register in time, then you're out of luck, but for those of you who did, good luck to you! Hope you chose your teams more wisely than I would have!
