I sort of like when Dana picks opponents to build someone he wants to be a star. It leads to the very best upsets and rivalries by accident. Some funny ones are intro level setup fights like JDS vs. Werdum and Lauzon vs. Pulver. I think Lyoto vs. Shogun I was a bit of a subtle set up fight to keep Lyoto champ while giving him another good stylistic opponent, and that turned into a great rivalry.
