Did you guys catch the BYU-Hawai'i matches? The second game was just crazy. After winning the third set, Hawai'i used the 90's style setter-middle-outside-hitter server sequence in the fourth set. Intentional or not, I think it was enough to rattle BYU, though it almost backfired as Hawai'i was called at least three rotation faults.
To me, the two matches proved that BYU is the team to beat.
