The team is peaking right now, at the right time.
Chris McGown, Men's VB coach, has always said that to win the National Championship, your team had to be playing its best volleyball year at the end of the season. The team cannot peak too early.
Olmstead seems to understand this. His previous two teams made it to the round of 16. Last year's team definitely overachieved without Hamson, IMO.
I think the setter change has added a new dynamic. It is working well, so Olmstead is sticking with it.
