One of the fan favorite traditions that comes with March Madness basketball is filling out your bracket and submitting it to the annual office pool at work. One of the hardest parts of correctly picking teams is anticipating those upsets that we all know are going to happen. This year, in order to efficiently outsmart that guy from accounting who wins every year, you must expect the unexpected and pick some of those lower seeded teams to beat the favorite.
VCU, Northern Iowa, Butler, and Davidson have all had their Cinderella story before taking down some of those pesky established programs in the NCAA. Butler has been continually making a run at a National title since Brad Stevens started coaching, despite being a low seed every year. They have established themselves as a premiere program and are a #6 seed this year. So if they do make a run at a championship this year, it really wouldn't come as much of a surprise as their incredible upset to Syracuse in 2010 did.
But part of what makes an upset special is that it's a team that doesn't do it every year. This is part of what makes March Madness so great. Anything can happen, and has happened in years past no matter what seed you are.
While impossible to predict, certain key factors can give NCAA basketball fans a better insight as to which upsets are bound to happen next. In 2010 it was the Butler Bulldogs making it to the National title. Last year, it was Dayton making it to the Elite 8 after beating heavily favored Kansas in the round of 32. This year, there are five upsets that should be on everyone's radar when they fill out those brackets in the next couple of days.
