Gonzaga has a much better OOC schedule than we do. To basically say we have the bare minimum required to get an at-large in the Tournament (if we go undefeated) isn't saying much. You want to increase your odds at getting into the tourney - because, like you said, that's what it's all about. This schedule minimizes our chances.
We aren't Gonzaga. We aren't going essentially undefeated throughout the season. But even if we could, it would still be preferable to have Gonzaga's OOC schedule and lose a couple of games.
