As the third part of a trilogy on SU football history, (with "Talent Level" and "Strength of Schedule"), I've decided to re-post something I did last year, analyzing the relative strength of SU teams by a system I call "Point Differential Rankings"
Some years ago I came up with a system for evaluating teams not only within particular years but also from different eras. It’s simple, (you can understand what the resulting number means without too much trouble), and it measures some very significant things: power and consistency. It also compares a team not just to it’s opponents but to it’s opponent’s opponents, giving the comparison a much stronger base.
Backstory
It dates from the 1991 SU-Florida State game, when an undefeated SU team took on the #1 ranked Seminoles with high hopes of an upset, having recently beaten Florida in the Dome. We jumped out to a 14-7 lead that could have been 21-7 except for a dropped pass in the end zone. We did it by getting quick developing plays off quickly and going right at the Noles who had greater team speed. Then, for some unfathomable reason, we dropped that strategy in favor of running the near-side option over and over again against a team that had more than enough team speed to stuff it, which they did every time. We went 3 and out the rest of the game while the Noles scored 39 unanswered points.
I was stunned that we’d abandoned a game plan that was working beautifully for one that had no chance of working, turning a possible upset that could have gotten us a #1 ranking for the first time in over three decades into a blow-out loss. People chalked up the defeat to the greatness of the team we were playing and the heat: what can you expect? The Florida State quarterback came over to Marvin Graves and told him “I don’t know how anybody gains any yards against our defense“.
But I wasn’t satisfied. I knew we weren’t 32 points worse than Florida State. I thought we could have beaten them if we’d stuck to the game plan. At the end of the season, I found that Florida State had played 13 games and of their 13 opponents, they beat only Western Michigan, (58-0) worse than they beat Syracuse. 11 of their 13 opponents did better against them than we did. That sounded like it was about more than how good they were and how hot it was.
I went through all Syracuse’s opponents that year the same way:
- We beat Vanderbilt 37-10. Of the 11 teams they played, only Alabama (48-17) and Tennessee (45-0) did better. So we were the 3rd best team they faced by point differential.
- We beat Maryland 31-17. West Virginia (37-7), North Carolina (24-0), Penn State (47-7) and Clemson (40-7) did better so we were the 5th best team they played.
- We beat Florida 38-21. That was the #1 performance against them all season.
- We beat Tulane 24-0. Florida State (38-11), Mississippi State (48-0), Alabama (62-3) and Southern Mississippi (47-14) did better so we were their 5th best opponent.
- We lost to Florida State 14-46. BYU (28-44), Tulane 11-38), Michigan (31-51), Virginia Tech (20-33), Middle Tennessee State (10-24), Louisville (15-40), South Carolina (10-38), Miami (17-16), Florida (14-9) and Texas A&M (2-10) all did better so we were the 12th best team vs. FSU.
- We lost to East Carolina 20-23. Illinois, (38-31) and Pittsburgh (23-24) did better so we were #3.
- We beat Pittsburgh 31-27. Notre Dame (42-7), Boston College (38-12) and Penn State (32-20) did better so we were the #4 team vs. Pitt.
- We beat Rutgers 21-7. Duke (42-22), Penn State 37-17), West Virginia (28-3) did better so we were the #4 team vs. Rutgers.
- We beat Temple 27-6. Alabama (41-3), Clemson (37-7) and Rutgers (41-0) did better so we were the #4 team vs. Temple.
- We beat Boston College 38-16. No one did better so we were #1, (actually tied with Michigan 35-13) vs. BC.
- We beat West Virginia 16-10. Pittsburgh (34-3), Penn State (51-6) and Miami (27-3) did better so we were #4 vs. West Virginia.
- We beat Ohio State 24-17. Michigan beat them 31-3 so we were the #2 team vs. the Buckeyes.
In shorthand, we were 3-5-1-5-12-3-4-4-4-1-4-2, a total of 48 “points” in 12 games, an average of 4.00, meaning that we were , on average the 4th best team our opponents played that year. It’s obvious that the Florida State game was a particularly poor performance by the 1991 SU team. We were between the 1st or 5th best opponent our other 11 opponents played. If you drop out the FSU game, our average is 3.27.
The natural thing was to compare this to SU’s two greatest teams, the 1959 national champions and the 11-0-1 team of 1987. The 1959 team played eleven opponents. They beat 9 of them worse than anybody else did. They beat Holy Cross 42-6 while Penn State beat the Crusaders 46-0. We beat Penn State 20-18. Pittsburgh beat them 22-7. Nobody else did any better than we did all year against any of our opponents. We were 1-1-1-2-1-1-2-1-1-1-1. That gave us 13 “points” in 11 games, or a rating of 1.18. You might think that is a typical rating for a national champion but, after spending a long time playing around with this formula, I found that the average post-war national champion is 2.30. In fact only one team in the post-war era did better than 1.18. The 1973 Alabama team beat 10 of 12 opponents by more than anyone else did. They beat Miami 43-13. Notre Dame beat them 44-0. Notre Dame then beat Alabama for the national championship, 24-23. But that was the closest anyone had come to beating Notre Dame all year so that got a #1 for the Tide, as well. That gave Alabama 13 “points” in 12 games or 1.08. But Bama got beat and didn’t win the national championship. The 1959 Syracuse team was and did. The may have been the outstanding college football team of the post-war era, (I never got around to checking the pre-war era).
The 1987 Syracuse team was 4-2-3-3-3-1-1-1-3-1-6-2 for 30 “points” in 12 games or 2.50. The #1 performances were vs. Penn State, Colgate, Pittsburgh and Boston College. Ironically the worst performance is the famous West Virginia game, a one point win. (The ’Neers also lost games by 2,3,4 and 5 points and by three TDs at Ohio State.) Colgate was not a “major college” (Division 1A) team. If you exclude them, SU had 29 “points” in 11 games or 2.64. The 1959 team didn’t play any teams that weren’t considered major college teams in 1959.
I realized I could use this procedure to evaluate teams across the years. It wouldn’t matter if it was a one platoon team or two platoons, if the era was high scoring or low scoring, if they ran more or passed more. The system measures two things: how well did you play and how consistently did you play well. The 1987 team was better than the 1991 team but much of the difference was that one bad game. We always hear that comparative scores are misleading but that’s less true if you look at all the scores. The system would appear to encourage running up scores but you can only do that on the bad teams and they will have other scores run up on them as well. Besides you can’t get better than a #1 rating. The real key is to avoid the bad game that pulls your average down, (like that Florida State game).
The 1959 Syracuse team played 11 opponents but those 11 teams played 65 different teams from every major conference in the country. This system thus compares Syracuse to those 65 teams by comparing how they did vs. Syracuse’s opponents. Thus it’s a very well “grounded” system. As I’ve used it over the years, the results have passed the “look” test. The right teams are at the top. If there is an anomaly, it likely means that a team is better or not as good as you might have thought. It’s not an iron-clad system for ranking teams: nothing is. But it’s something that should be looked at before you decide who is better than whom. If you disagree with the results, you will need to construct an argument around them. That’s the purpose of statistics: to provide an objective foundation for a discussion or debate. In college football it’s not enough to be good: you’ve got to be consistently good. That’s what this system measures.
There’s two websites that contain all the scores for all the major college football teams in history:
http://www.jhowell.net/cf/scores/byName.htm
http://www.phys.utk.edu/sorensen/cfr/cfr/Output/CF_History.html
They can be used to make these comparisons easily. One limitation is that they don’t list schools that were not considered major college or not in a particular year. You thus can’t use these sites to rank the performance against such teams. I have other sources for this information but I decided instead to ignore games vs. non-major college teams, since we were likely the best team they played to begin with. Thus the 1987 team is a 2.64 team, not a 2.50 team because I‘m not counting the Colgate game. I do use all games of each opponent to rank SU’s performance vs. that opponent. If a small college team did better than we did against an opponent, that should count.
I do not count service teams, either as an opponent to be checked out or as an opponent’s opponent who might have beaten a team worse than we did. Service teams are not four year colleges. They don’t obtain players in the same way and are often all-star type teams. However I do include service academiesas they are four year schools.
