Just my opinion and I don't have access to the data that Roth/Few and the WCC has but:
I couldn't agree more that they should skip it. The year itself is so soft in terms of deserving teams (except in the Big 10, Big 12), that I think a second WCC team would be able to claim it's earned.
And I think it delivers max protection to GU (I am assuming the data bears this out, I could be wrong).
This team's unique focus should be on the NC, they are so much better than every team but Baylor that the WCC would mean almost nothing this year, while also presenting a few dangers in travel.
If the NCAA puts the tournament off until April - something that should also be strongly considered, then I think the Zags would be served by playing in a delayed WCC tournament.
I am positive Roth will make the right decision.
Whenever you find yourself on the side of the majority, it is time to pause and reflect.
