The time has finally come and a lot of fans are hoping that come Sunday night at 6 p.m. ET, the team of their choice will eventually become this year's national champion.

As things stand now, there seems to be minimal changes on who the top teams would be.

Leading the pack is no other than tournament favorite Kentucky (Wildcats) who seem poised to win it all. But standing in their way are other favorites which include the Virginia Cavaliers, Duke Blue Devils and the Villanova Wildcats, all of which are expected to end up as the number one teams to lead the four regions (East, West, Midwest and South).

Upsets are of course not being discounted but as things stand now, these are the favorites.

As for the selection process, such promises to be a tedious one. It is not a matter of simply selecting and placing a team since there are a lot of other factors that need to be considered. This includes weighing statistics and taking another look at snubbed teams.

And while lower seeded teams are normally seen to be the ones to be given the boot, surprises and upsets could still happen. And much of the attention comes in the brackets were 12 and 5 seeds are placed.

History has shown that 12th seeds have had their luck toppling the higher seeded ones and based on the performance of most squads, this could happen again.

But then again it all depends on the selection process where perfectly filling out each bracket is a rarity.

Whatever the case may be, there may (or could) be surprises and everyone knows it all too well.

The clock is ticking and Selection Sunday is fast approaching. Don't miss out on the madness which starts this March 15 at 6 p.m. ET on CBS and will continue up to April 6. Selection Sunday will be available to watch online via live stream on CBS, via All Access. Printable brackets are available here.
