Since March Madness became part of the sports vernacular, the NCAA Tournament bracket pool has become a familiar exercise. Broadly speaking, participants come from two main categories. There are the more casual fans who only pay attention to men’s college hoops around tourney time. They’ll do a modicum of research but will for the most part rely on name recognition and seeding to fill out their brackets.

Then there are the diehards, those who follow the sport from November onward in hopes of accumulating more knowledge for when the bracket is finally unveiled.

March Madness bold predictions: Best upset picks, Final Four sleeper

This is for the latter group, the ones who have been watching certain teams all season and are all too aware just how wildly unpredictable they can be. These are the teams that will cause self-described bracket experts the most angst as they consider their picks. They’re the teams that have the talent necessary for a deep run, even perhaps capable of sending a No. 1 packing. But they are also inconsistent enough that they’re just as likely to flame out in the first weekend. As you consider what to do with these eight teams, all we can say is, good luck.

The Jayhawks’ history with Bill Self at the helm suggests their Final Four potential shouldn’t be dismissed. Their Big 12 results this season were a mixed bag, however, with impressive wins against Arizona and Iowa State mingled with ugly losses to bottom-tier finishers West Virginia and Arizona State. KU’s inconsistency isn’t entirely attributable to Darryn Peterson’s inconsistent health status, though that is certainly part of the story. Flory Bidunga can be dominant at times and invisible at others, and Melvin Council Jr. can be sizzling hot or ice cold.

The Boilermakers were voted No. 1 in the preseason poll. At the start of the campaign and again at the end they looked the part. In between, however, they presented as a middle-of-the-pack Big Ten squad, a curious situation for a team with several multi-year starters. When Purdue struggled, there were issues at both ends of the floor, at times disinterested on defense and making bad decisions with the ball. Did the Boilermakers figure things out at the Big Ten tournament, or will there be a relapse at an inopportune time?

There are many reasons to back the Razorbacks in their region. Their SEC tournament title would seem to indicate they’re heating up at the right time, and coach John Calipari has taken his share of teams to the final weekend. But their path to the SEC championship was cleared for them a bit as they didn’t have to face Florida or Alabama, and as good as Darius Acuff Jr. has been over the last few weeks, only a few teams have gone the distance with a talented freshman lead guard.
