The betting favorites in the NCAA tournament went on a historic run over the weekend, leaving a Sweet 16 bracket full of blueblood chalk.
For the first time since the NCAA tournament expanded to 64 teams in 1985, all 16 betting favorites won in the Round of 32, according to ESPN Stats and Information.
Three times, in 2009, 1995 and 1991, the favored team had won 15 of 16 games in the Round of 32, but this was the first year in which the chalk went undefeated.
Many of the favorites won in blowout fashion, too: Eleven of the 16 games were decided by double digits, with North Carolina and Michigan State among five teams that won by 20 or more.
