NCAA Brackets- Help Me!

I need your help my company Townsquare Media is giving away one million dollars for the perfect NCAA bracket. You can sign up to be a part of the million dollar bracket now. I have to put together a bracket too and that is where I need your help. What teams should be on my radar, who do you think the best college team in the nation is? Is it ok to pick Arizona just because I went to school there? What team is the underdog? Any help in building my NCAA bracket would be mucho appreciated and did I mention there is a million dollars in it for you- only if you sign yourself up to play and score the perfect bracket.
