On March 13, Selection Sunday will take place as the season winds down for the highly awaited month of crazy college basketball.

The tournament is considered unpredictable, seeing constant change at the top. This season alone has seen six different teams at the number one spot, which is evidence that it will be a pretty wild and wooly National Collegiate Athletic Association (NCAA) March Madness, according to Oklahoma athletic director and Selection Committee chairman Joe Castiglione, as reported by NCAA.com.

Castiglione will be meeting up with the committee in Indianapolis to evaluate all 336 eligible schools after which a mock draft will reportedly take place.

He added that while it's normal to have nine to eleven conferences which would see multiple teams sent to the tournament, there is a chance that he could expand that to 14 leagues for multiple bids in the event that one of the teams do not qualify for an automatic berth. That is if things play out a certain way in conference tournaments.

With that said, Castiglione explained that the thought alone should make a good account for the unpredictability this season.

So if that were the case, this season could end up far different from last year where eight teams locked in at the top two lines. Based on what has happened thus far this year, such may not be the case and such could promise better games for the fans.

Making the selection process a bit tricky this year are also the changes made. Castiglione pointed out also via NCAA.com that 30 teams averaged 75 points per game last season and now, 139 are scoring at that range.

Two teams who would have been strong contenders were Louisville Cardinals and SMU Mustangs. Unfortunately due to violations of NCAA rules, they have become ineligible.

But Castiglione cleared out that teams who played against the two teams are valued the same, meaning games against them will be included in all metrics.
