When no one is staffed at that time... I don’t know why you’d expect something published online short of breaking news.
30 minutes. That's all it would have taken.
If the editor is worth a ****, they'd know when the selection show is. They would also know that ISU was a lock, and that UNI was on the bubble -- at least, they would know if they had bothered to even acknowledge that those teams existed.
Knock out 250 words with the basics, set it to post at 6 a.m., and tag the story with a teaser ("More details in Tuesday's edition"). Easy peasy.
Just laziness and/or indifference.
