We've heard all we can about the dreaded 5/12 upset. Every year (it seems) a five seed drops a game or two or three against a twelve seed. That's what faces Utah today against Arizona, the possibility of being upset in the first round. But is it really a cause for concern? Well maybe not, especially with Western Kentucky's victory over Illinois yesterday. 

Here's a look at how every five seed has faired since the 2000 season. We'll begin with the 2009 tournament and move backwards, to see if this is really an issue facing the Utes.

Kentucky - Defeated St. Bonaventure and lost to Syracuse (4) in the second round.

Texas - Defeated Indiana State and lost to LSU (4) in the second round. 

So there you have it. A lot to digest, however, roughly 65% of five seeds have advanced beyond the first round. That isn't an extremely high number when you consider the seed discrepancy, but it's still decent enough, especially with one five seed already going down (Illinois). 

Of course, the most interesting thing I found out from this was how successful five seeds are in reaching the Sweet Sixteen when they beat their first round opponent. 

In every tournament this decade, at least one five seed has reached the Sweet Sixteen. It's happened a total of 15 times in eight years, which means if you're a five seed and you make it into the secound round, you actually stand a pretty good chance of at least making it to the regional semifinals. 

Unfortunately for Utah, it's not very likely they make it beyond the Sweet Sixteen if they do advance that far. Only three teams own extremely deep tournament runs as a five seed: Michigan State (Final Four, 2005), Indiana (NC game, 2002) and Florida (NC game, 2000).

So what does this tell us? Well upsets happen with these pairings, but they're not as common as some would lead you to believe.

If you play it by the odds, and I know some totally discount that theory, Illinois' loss is a boon for Utah.

But we'll see...
