RALEIGH (WTVD) -- After a wild first day of the NCAA Basketball Tournament, just 14,525 -- or 0.1 percent -- out of the approximately 13 million Tournament Challenge brackets submitted to ESPN were a perfect 16-for-16 on Thursday.
In comparison to previous years:
Another 182,678 brackets went 15-for-16 on Thursday. On the other end of the spectrum, seven brackets laid an egg, going 0-for-16 on Thursday.
The twin upsets by 12-seeds Yale and Arkansas-Little Rock over Baylor and Purdue, respectively, really shook up the field. Plus, a pair of upsets by 11-seeds -- Gonzaga over Seton Hall and Wichita State over Arizona -- heightened the bracket-busting madness. Overall, the better seeds went 9-7 on Thursday.
