It is really, really hard to go undefeated. Some of our best teams have failed to accomplish it.
You can't have an off-game against a top-5 team. Our conference schedule will be a joke, there will still be 5-8 tough games, including, obviously, the Final Four. Fortunately, our main competitors, the programs who have actually won something (ND, Stanford, Baylor) are losing a lot. I don't see pretenders like UNC actually accomplishing anything on the national stage, and Tennessee is probably still a year or two away.
But we'll have to dodge a lot of bullets to avoid losing a single time.
