Well sure there is. There are 351 D-1 teams and only.... 4 can make the Final 4. The odds are extremely long for just about every team. I would say mathematically impossible to "expect" more than about one or two teams to make it preseason, and some years there's not really any single team that was likely.
Consider that the Kenpom odds generator (
http://kenpom.com/blog/2017-ncaa-tournament-forecast/) only gave us a 20% of making the Final 4 pre-tournament, and that was after seeing us dominate all year. The only team with higher odds was Gonzaga, and only 4 teams even had a 10% chance of making it.
I think given the crapshoot nature that you mention, it is very fair to expect we won't make it. Maybe unfair to expect that we won't be a top 10 team, although I think there's a decent shot of that too.
