Klingman: Margin of victory should have a bigger team impact

In a sport that values domination, high school and college wrestling seems out of touch with its own standard.
We call it a blowout if a football team beats another team, 70-0. If a basketball team wins 100-50, we call it improbable. If a wrestler wins, 1-0, 10-5, 11-4, 14-7, 3-2 or 8-1 we call it a regular decision.
Regardless of how competitive a wrestling match is, one team gets all the points and the other team gets nothing.
The above sports comparisons are a bit skewed, of course. A 7-6 win in wrestling equates to a 70-60 win in football, and basketball allows its participants to score more points throughout the course of a 48-minute game.
Regardless, there is no denying this: A 1-0 win in college wrestling is worth as many points as a 14-7 win (3 team points), and a 14-0 win is worth as much as a 16-8 win (4 team points).
Although dual and tournament scoring is antiquated and amiss, there is a solution to add more excitement to our sport and to add a meaningful statistic to a sport that values a win-loss record above all else.
The NCAA currently awards the most dominant wrestler of the year. The highest possible score is a 6, which means a wrestler went undefeated and pinned everyone he faced. Every decision is worth 3, a major decision is 4, a technical fall is worth 5 and a fall is worth 6, while the opposite is true if you lose by the predetermined amounts.
Penn State’s Zain Retherford ended the 2018 season with a domination index of 5.19 — a staggering number to be sure.
There is likely a better way to track the efficiency and effectiveness of a wrestler during the course of a season and a career that does not include arbitrary standards.
Through conversations with Andy Hamilton of Trackwrestling.com — a baseball fanatic who is in tune with the statistical side of America’s pastime — we created a statistic that can enhance the value of the sport at the college and high school level.
We are both concerned that wrestling does not have a statistical narrative that keeps fans engaged. Our new wrestling statistic is a point differential index (PDI) that rewards a wrestler for winning by large margins and, the ultimate, securing falls.
PDI is less about wins and losses and more about scoring points.
If a wrestler wins by 10 points, he gets 10 points. If a wrestler loses by five points, he loses five points.
Simply, a wrestler’s margin of victory or margin of loss determines the numerical value that is tabulated into the overall PDI.
A fall is given a value of 22 points since a technical fall can be worth up to 21 points. If a wrestler is leading by 14 points and secures a six-point move (two for the takedown and four for the nearfall), then he would win by 20 points. A wrestler could also pick up a riding time point, which is a 21-point technical fall.
No points are awarded if a wrestler receives a forfeit. PDI is about matches that actually take place.
Remember, this is about assigning a numerical value to a wrestler as a way to show domination. That’s why scoring as many points as possible helps a wrestler’s PDI — even if he loses.
Retherford’s PDI for the 2018 season was a jaw-dropping 17.2. That means lots of falls and some technical falls that were higher than a 15-point differential. Despite two losses on the season, Iowa’s true freshman Spencer Lee had a PDI of 14.5.
There are two complications with a PDI:
1.) PDI does work to make historical comparisons. Dan Gable, Wade Schalles, and Gene Mills would have a very high PDI, but there weren’t technical falls during their eras so a value can’t be given to a fall. There was only a five-point near fall when Cael Sanderson wrestled, which makes a more reasonable comparison.
2.) PDI does not factor in strength of opponents. A wrestler who faces tough competition throughout the season might have a lower PDI than a wrestler who is injured or who doesn’t face anyone in the top 10.
PDI is designed to show the overall effectiveness of a wrestler. It also allows fans to make comparisons, which is healthy for any sport.
Quality statistics force us to consider a better way of tracking our sport. The current way isn’t as effective as it should be.
