Niskie's very well liked, Malibu has a lot af friends, kkk made it out of the last 16 by beating me (and belive me, I'm far more biased towards me) and Carnival has always defied the laws of natural selection. When you compare it to this years tournament, when your last eight is going to include two posters from the mediocre bracket, I'd say it's stronger. Besides, it's no easier than Czech's, or potentially your, route to the final eight this year.
I think the final last time out was a suitable one. Maybe next year, it's worth seeding everybody in the 64 and doing it that way.
