And even without that one it's kind of splitting hairs.
2024 lost by 17, 60-77 to Creighton
2022 lost to UCLA by 4, closest loss ever 53-57
2013 lost by 46! 🤮 to VCU 42-88
2011 lost to Notre Dame by 13, 56-69
2009 lost by 13 to Gonzaga 64-77
1986 lost by 6 to Michigan 64-70
So 17 isn't great but isn't that out of line.
BTW our seeds in those games starting with the most recent were 14, 13, 12, 15, 13 and 15.
