I write about how statistics can be used to help understand sports, but these techniques and tools have applications in quality improvement and any other endeavor that involves the analysis of data. Continue Reading »

If you're scared this is what the playoff will look like, just remind yourself that Georgia Southern beat Florida this year without completing a pass. Auburn beat Alabama this past weekend in one of the most incredible endings you’ll ever see. The stakes couldn't have been higher. With the defeat, Alabama lost any realistic shot at playing for the national championship this year. However, if this... Continue Reading
I know we lost by 2 touchdowns, but if only you had given Peterson 3 more carries we would have won! Last week, ESPN ran an article about why the running game still matters. They used statistics to show that the more you run the football in the NFL, the more likely you are to win the game. Specifically, if you have a running back who gets at least 20 carries, you win about 70% of the... Continue Reading
Last week I took a look at some different aspects of overtime in college football. I found that most games only last one overtime period, home field advantage still exists, and that the team that gets the ball 2nd has an advantage. Now I want to continue the data analysis and ask some more questions. Specifically, how many points do teams combine for in overtime, and does the team that ties the... Continue Reading
Two weeks ago Penn State and Michigan played in a quadruple-overtime thriller that almost went into a 5th overtime. Had Penn State coach Bill O’Brien kicked a field goal in the 4th overtime instead of going for it on 4th and 1, the game would have continued. But the Nittany Lions converted the 4th down (which, by the way, wasn’t a gamble) and went on to score the game winning touchdown in the 4th... Continue Reading
If you like football and you like video games, you must certainly be aware of the “Madden Curse.” Each year, EA Sports releases a new version of Madden, a video game based on the National Football League. Each version of Madden features a different NFL player on the cover of the game. And it seems that each year, the player featured on the cover gets hurt or has a terrible season. Thus,...

On Saturday, September 8, 2012, Penn State football player Sam Ficken had a kicker’s worst nightmare. Playing against Virginia, he missed 4 field goals, including the potential game-winner as the game ended. To add injury to insult, he also had an extra point blocked. Penn State lost the game by a single point. At that point in his career, Ficken had made 2 out of his 7 field goal attempts. That... Continue Reading
In the world of Six Sigma, we’re always looking to improve our process. Whether it’s increasing the strength of building materials or improving the way calls are processed in a call center, it’s always a good idea to use a data-driven analysis to determine the best solution to your process. The same is true for the NFL. Two years ago, the NFL decided to move kickoffs up from the 30 yard line to the... Continue Reading
Ever start a fantasy football draft and realize that passing touchdowns are worth 6 points, not 4? Or how about realizing at the last minute that the commissioner of your league decided to have a point per reception (PPR) league. We know that this year running backs are going to be going early in the draft. But if your league is a PPR or gives 6 points for a passing touchdown, should you... Continue Reading
When it comes to fantasy football, there is a common statistical term that comes up again and again. It’s "variation." From season to season, week to week, and even quarter to quarter, NFL players can be very inconsistent. This can make selecting your fantasy team as much about luck as it is about skill. Nobody has a crystal ball that reveals who will be fantasy sleepers and fantasy busts in the... Continue Reading
Last week I used Minitab's paired t test to compare how quarterbacks and running backs performed the season after finishing in the top 3 in fantasy points. Quarterbacks did not perform significantly worse, while running backs scored about 80 fewer points and finished ranked 8.7 spots lower than their top 3 year. Now it's time to move on to wide receivers and tight ends. Will they follow suit and... Continue Reading
In 2006, LaDainian Tomlinson set an NFL record by scoring 28 rushing touchdowns. The next year he had about half of that, only scoring 15. In 2011, Calvin Johnson caught a ridiculous 11 touchdown passes in the first 8 games of the season. In his next 24 regular season games, he caught 10. In 2007 Tom Brady set an NFL record with 50 touchdown passes. In each of the 5 seasons after that, he... Continue Reading
We’re 93 games into the Major League Baseball regular season, and for the 3rd year in a row the Pittsburgh Pirates have a winning record. Unfortunately for Pittsburgh fans, the previous two seasons have ended with collapses, making the Pirates the first professional sports team to have 20 consecutive losing seasons. Optimists say 2013 is finally the year they snap the streak, while pessimists see... Continue Reading
LeBron James has just captured his 2nd NBA Championship in as many years, and has secured himself a place as one of the greatest basketball players of all time. And he even did so by overcoming the “Winner of Game 3 wins the series 92% of the time” odds. With the victory, there is a 99% chance the “LeBron is a choker and can’t win the big one” narrative is dead and gone (I say 99% because I’ll... Continue Reading
Have you heard about the Tennessee man who has 22 children to 17 different women? He was interviewed the other day, and when asked how he supports all his kids he was quoted as saying: "I'm just hoping one day I'll get lucky and might scratch off the numbers or something. I play the hell out of the Tennessee lottery." Well, what would it look like if a person really did play "the hell" out of the... Continue Reading
I previously started looking into which method of gambling was your best bet: a NFL bet, a number on a roulette wheel, or a scratch-off lottery ticket. After calculating the expect value for each one, I found out that the NFL bet and roulette bet were similar, as each had an expected value close to -$0.50 on a $10 bet. The scratch-off ticket was much worse, having an expected value of -$2.78. But... Continue Reading
New Jersey Gov. Chris Christie is currently in a battle with sports leagues over the issue of allowing sports betting at casinos in Atlantic City and horse racing tracks across the state. If he wins and sports betting becomes legal in New Jersey, it will open the door for other states to follow suit. It appears there is a long way to go before this form of gambling spreads across the country. But... Continue Reading
The Pittsburgh Penguins are in the midst of another Stanley Cup playoff run. With a 3-1 lead over the Ottawa Senators, they are a mere 1 game away from their 3rd Eastern Conference Final in 6 years. But it looks like they will do so without starting goalie Marc-Andre Fleury.After a string of disappointing playoff games, Fleury has been benched and netminder Tomas Vokoun has been guarding the goal....

After another round of what seems like endless conference realignment, the Big Ten has settled on 14 teams split into two divisions; East and West. However, with the likes of Ohio State, Penn State, Michigan, and Michigan State, the East division appears to be much stronger. In fact, Indiana athletic director Fred Glass called it the “Big Boy Division,” and Penn State coach Bill O’Brien referred... Continue Reading
In my previous blog post, I analyzed the madness in this year’s NCAA tournament for games through the Sweet 16. I found that it was one of the wackiest Sweet 16s ever. But things didn’t stop there—the Final Four was pretty crazy, too, having two 4 seeds and a 9 seed! So now that the tournament is over, I want to look back and see what were (statistically speaking) the most unlikely things to have... Continue Reading
Cinderella showed up early and often during the first weekend of the 2013 NCAA Tournament. Florida Gulf Coast stole the show with their glass slippers, becoming the first ever 15 seed to reach the Sweet 16. But don’t let that overshadow what happened in the West Region: Wichita St and La Salle both arrived in a pumpkin-turned-carriage, and now the Shockers are a game away from the Final Four! And...
