In part 1 of this series, I looked at which teams were upset the most. In the end, the Oregon Ducks were crowned the Most Overrated Team. Now it's time to look at everyone's favorite teams: the underdogs that pulled it off.
Once again, I'll show you the data in 2 ways. First, I'll show which teams have pulled off the most upsets in total. Second, I'll show which teams have the best Upset %, which is the % of times they pulled off the upset when in a position to do so. I'll also filter out teams that have been underdogs fewer than 20 times for 1998+ data and 6 times for 2014+ data.
In part 1, I defined an upset as a game in which:
Since 1998, there have been 6,335 games that could have ended in an upset. I will call these games "upsettable". 1,301 have ended in an upset, or approximately 20.5% of them. Since 2014, there have been 2,207 upsettable games, with 21.4% of them ending in an upset.

8 Teams appear on both lists: Stanford, Arkansas, Texas A&M, Auburn, Ole Miss, LSU, Texas, and Oklahoma State. These 8 teams have been consistently pulling off upsets since at least 1998. Surprisingly, 5 of those teams are also on the list for most times being upset: Texas A&M, Auburn, LSU, Texas, and Oklahoma State. Part of the reason for this may be knee-jerk voter reactions. In other words, these teams will pull off an upset, jump high in the polls, then lose because they weren't actually deserving of their ranking.
LSU comes in at #3 in Most Upsets since 2014 and tied for #2 since 1998. They also come in #1 in Most times being Upset since 2014 and #4 since 1998. The Tigers must be true fans of chaos.
While total upsets is fun to look at, Upset % is a better stat.

While LSU was #3 in Most Upsets since 2014 and tied for #2 since 1998, we see here they are #2 and #1 in Upset % in those same timeframes. Only 2 teams are on both lists with the aforementioned Tigers of LSU being joined by Miami. Miami, however, is being trailed tightly by TCU since 2014. By the end of this year, LSU may sit as the lone crossover between these 2 lists.
Not every team is good at pulling off the upset. We saw in Part 1 that some teams simply don't get upset very much at all, such as Cincinnati and Alabama. Let's take a glance at the teams living up to their lower/non-ranking.

These lists are probably similar to what you expected to see. A couple of notable standouts include Cincinnati, who evidently doesn't pull off upsets or get upset, and Nebraska. The Huskers have fallen off dramatically recently. From 1998-2013, they were 9-27 in upsettable games, a fairly pedestrian 25%. That number has dropped to ~9% since 2014 though.
Upsets are always fun to watch. Unless your team is on the losing end, of course. But there are 2 types of upsets that just have a little extra excitement: upsets by unranked teams and upsets over Top 5 opponents.
For these lists, 3 columns are shown. Unranked is the number of times they won as an unranked team. Total is the total number of times they won. Unranked % is the % of upsets in which they were unranked.

As expected, several teams appear on both lists. Virginia's Unranked % stands out. Since 1998, Virginia has pulled off 20 upsets. They were unranked in all 20. Arizona is similar, with 17/18 coming as an unranked team.
For these lists, 3 columns are shown. Top 5 is the number of times they upset a Top 5 opponent. Total is their total number of upsets. Top 5 % is the % of upsets in which they defeated a Top 5 team.
Team | Unranked | Total | Unranked % |

Team | Top 5 | Total | Top 5 % |

To perhaps nobody's surprise, it generally takes the best to beat the best, with teams such as Alabama, Ohio State, and Florida leading the way. The biggest surprise may be Purdue, though their success against top 5 teams has been well chronicled.
Several things can be gleaned from this data.
That concludes part 2. In the next few days, I will try to upload a list of all teams' upset stats in a searchable table. Until then, enjoy the chaos of college football.
