There is only one time a year a blank PDF copy of the NCAA Tournament bracket is needed.

No, not the one at which we all stare trying to figure out matchups and who will make a run between Sunday night and Thursday. The literally blank bracket on which you fill in the teams when they're announced.

That one time is between 6 and 7 p.m. on Selection Sunday.

Even in this age of instantaneous technology and information exchange, there is still something about filling in teams on a blank bracket, an anticipation of hearing about who will make it into the Big Dance.

That something fades away after the brackets are filled in after 7 p.m. on Selection Sunday and can be printed and dissected as forests everywhere become endangered.

But it's still fun while it lasts.

So while we all hear about NCAA "corporate champions" and bubble teams, just like I have for most of my life, I'll also be parked in front of the TV with a pen in my hand.

That anticipation, just like that CBS Sports intro music on the opening Thursday of the tournament, never gets old.
