Of course it is not out of the question. However, losing 50% of your scoring is also not a "no big deal".
As we all know, the NCAA Tournament relies on a lot more than just skill. Last year, we didn't really get a break in terms of seeding, but Villanova was a great match up for us for example in what can be a tricky 3/6 match up (a team that switches on every screen). And we got hot at the right times - particularly certain players. Ryan Cline doesn't go off against Tennessee, no chance we win that. Carsen doesn't go off in the second half against UVA, no way we're in overtime. But it's also a reason to be optimistic going forward where we'll see a more balanced offense and we won't rely on this or that person to have a game of their lives to be able to beat a top team.
Any team in the top 7 seeds you can say "is not out of the question" on a Final Four run. If you really want to look at expectations, 2021 would be the year to circle given our roster stays intact.
