Thought this was some interesting data tracking comebacks and blown leads over the last decade.
Arkansas has blown 15 leads of 10 or more points since 2007, which is tied for the most in the nation over that time span. Texas A&M and Western Kentucky have also blown 15. Ironically, a few of the Arkansas-Texas A&M games featured rallies reflected in those totals.
According to this, Arkansas has come back to win three times after being down 17 or more, which is one of the highest numbers out there. Florida State was first with five and a few teams had four.
