That's the way the NCAA tourney works... Number 1 seeds (KY) play against #16 seeds; #2 plays #15, etc.
The objective is to have the 4 best teams in the country, i.e. the four #1's, meet in the Final Four.....of course, that almost never actually happens.
I KNOW THAT! what do you think i am some neophyte?? ; ) i am just giving you a small bag, is all!
