I have a whole array of which teams get there. Kentucky is my only consistent one. Bottom left, sometimes Wisc, sometimes Arizona. Top right, sometimes Oklahoma, usually Virginia (and usually Virginia to the finals). Bottom right, usually Gonzaga (getting to the finals when Oklahoma is my top right, losing to Virginia if it's Virginia) and sometimes Iowa St to lose to top right. I think I have Duke in the final 4 once, but hate them enough to not pick them more than that, even if I think it's a reasonable shot.
Never Kansas, because I always have them going out to Wich St. Never Nova, because I don't think they beat either Virginia or Oklahoma. Kentucky to win the bracket on every one of them.
