Selection Sunday is here. The official beginning of March Madness is just days away.
As soon as CBS' Greg Gumbel is finished telling us who is in and where everyone is playing, priority one is to fill out your bracket.
Whether you fill out one bracket or many, choosing how to go about it may make or break your chances of winning the pool(s) that you enter.
One way that you might go about making your choices is by looking at the first-round results from past tournaments and pick some upsets.
Remember: There's always insanity at the beginning of the NCAA tournament.

By checking out how the first round has gone in those 26 tournaments, you might be able to make your decisions on this year's 32 opening games (not including the play-in games).
So, if you are looking for a little statistical info on some possible upsets, here's how you can fill out the first part of your bracket by the numbers.
