Iowa State win over LSU busted all remaining perfect brackets

It’s unclear how many perfect brackets remained as tipoff neared, but it was unlikely to be many. The tournament has been defined by bracket-wrecking upsets early on, including No. 11 Notre Dame over No. 6 Alabama, No. 12 Richmond over No. 5 Iowa and, of course, No. 15 Saint Peter’s over No. 2 Kentucky.

At the time of Kentucky’s loss, only 3% of all brackets were still perfect. Iowa State’s victory eliminated those.

With all remaining brackets flushed, it marks the second consecutive year in which no perfect brackets remained after the first round.
