They've got South Dakota as their opener this year. South Dakota only played two games last year. Surely they'll win that one.
Incorrect. They didn't play any games last year. They're playing spring football, currently underway. They're 1-1 right now, with 7 more games to play.
They went 5-7 in 2019.
However, I do agree with you that it will likely be KU's only real shot at winning. Thanks to covid, those fighting jayhawks were able to avoid taking the field 3 times last season, and only acquired 9 losses. For those who are keeping track, that means they currently have 89 losses in the last 9 years. So, they can win, at most, only 1 game next season if they are to achieve greatness, and become the first program to have 100 losses in 10 years.
