Previous to additional time final Sunday night time, together with his workforce in jeopardy of beginning a pivotal season with two straight losses, Indianapolis Colts coach Shane Steichen contemplated one of many hardest selections in soccer.
He needed to determine whether or not to kick or obtain if the Colts gained the coin toss.
Successful the additional time coin toss was trigger for celebration beneath the NFL’s earlier guidelines. The receiving workforce gained the chance to safe victory with out its opponent touching the ball if it scored a landing on its opening possession.
The optimum technique is much murkier now that the NFL’s additional time system ensures each groups possession of the ball. Successful the coin toss now means selecting between taking the ball first to chase a possible possession benefit or taking part in protection first to know precisely what number of factors are required to win.
The presence of quarterback Patrick Mahomes within the opposing huddle influenced Steichen’s determination to provide the Kansas Metropolis Chiefs the ball to start out Sunday’s additional time. As Steichen informed reporters after the sport, “If we go first with it, Mahomes will get 4 downs going the opposite means, so we wished to play protection there and know we had 4 downs.”
Steichen’s determination backfired on the Colts when each groups settled for area objectives on their preliminary possessions of additional time and Mahomes took benefit of getting the ball a second time. l despatched the Chiefs spilling onto the sphere in celebration and sparked renewed debate over how groups ought to method profitable the additional time coin toss.
It’s tough to attract significant conclusions from the outcomes of latest additional time video games as a result of the pattern dimension is simply too small. Twenty video games have gone to additional time for the reason that NFL adopted the brand new guidelines for the playoffs in March 2022 after which prolonged them to the common season in 2025. The workforce that gained the additional time coin toss has chosen to kick in 14 of these 20 video games. And but the workforce that acquired the ball first is 11-8-1 (57.5%).
A examine printed by a football-obsessed heart specialist in The Journal of Sports activities Analytics this previous July supplied among the first mathematical perception into the optimum technique for the NFL’s kick-or-receive additional time coin toss dilemma. Utilizing a Monte Carlo simulation to foretell which technique would show advantageous over 100,000 NFL overtimes, writer Dylan Goings discovered that electing to obtain the ball first would produce a win price of 53.14%.
“Coaches who select to kick are buying and selling a structural positioning benefit for informational readability that, in our evaluation, doesn’t translate to improved outcomes,” Goings concluded.
Goings informed Yahoo Sports activities he took on the undertaking in his spare time final January after he and a few faculty buddies obtained right into a spirited debate over whether or not the Chicago Bears have been proper to kick the ball to the Rams at the beginning of additional time within the divisional playoffs. The heart specialist couldn’t let the argument go unresolved, particularly not when his background in medical analysis, danger stratification and statistical evaluation gave him the instruments to discover a definitive reply.
“It’s simply the kind of particular person I’m,” Goings stated with fun. “In case you have an argument with a pal and you’ve got a hunch that you just’re proper, let’s settle it.
“I had already written code to do a Monte Carlo evaluation for one thing very comparable. So with only a few tweaks I had one thing that's related to soccer followers.”
The important thing limitation to a Monte Carlo simulation — an evaluation that makes use of random guessing again and again to foretell the attainable outcomes of an occasion — is that the outcomes are solely pretty much as good because the assumptions and possibilities that the researcher feeds into the simulation. Goings combatted that earlier than submitting his examine for publication by posting the outcomes of his Monte Carlo simulation to a handful of Reddit boards and incorporating suggestions on how closely to weigh variables like two-point conversion technique or clock strain.
“It was like a peer overview course of from strangers on the web,” Goings stated.
To check whether or not the optimum technique various if one workforce had an elite protection or a turnover-prone quarterback or a shaky kicker, Goings performed a sensitivity evaluation utilizing excessive and even unrealistic efficiencies. There was no mixture of variables, he stated, the place he discovered it was extra advantageous to kick than to obtain.
One of the best ways for the workforce that has the ball second in additional time to eat into its drawback, based on Goings, is to aggressively go for the win on its preliminary possession. Whether or not by going for it on 4th-and-short as a substitute of kicking a tying area aim or trying a two-point conversion as a substitute of kicking a tying additional level, these choices are superior to matching scores and giving the opposing workforce possession of the ball within the sudden dying format.
One of the crucial certified folks to evaluate Goings’ findings may be a former backgammon world champion with a ardour for recreation principle. > has labored with risk-averse NFL and faculty coaches to assist them optimize their in-game determination making, first as a co-founder of knowledge evaluation agency EdjSports and now as an impartial guide.
When requested which technique he favored for the additional time coin toss winner, Frigo informed Yahoo Sports activities that he believes the potential to have a better variety of possessions by taking the ball first barely outweighed the informational benefit of getting the ball second. Frigo hasn’t run a full knowledge simulation like Goings, however he pointed to knowledge exhibiting that 22.1% of NFL overtimes finish on the third possession and 6.4% on the fifth.
“It's onerous for me to think about that the informational benefit of getting the ball second outweighs that,” Frigo stated.
As followers in Buffalo know all too properly, the NFL carried out its new additional time system in response to the Kansas Metropolis Chiefs beating the star-crossed Payments within the divisional spherical of the NFL playoffs in January 2022. After an exciting, back-and-forth 60 minutes of regulation, the additional time coin flip had an outsize affect on the end result. The Chiefs gained the toss, and Mahomes promptly led them to a landing on the opening drive of additional time, stranding Josh Allen on the sideline with no solution to reply, no solution to affect the end result.
The shortage of debaste over whether or not the kicking or receiving workforce has the benefit in additional time now could be proof that the NFL’s new system is working. For the reason that begin of the 2025 common season, the additional time coin toss winner has a file of 6-12-1.To today, groups don’t appear to totally perceive easy methods to capitalize on the slight structural benefit of receiving the ball first or easy methods to negate a lot of the drawback of taking the ball second by taking part in for the win.
After his workforce misplaced 20-17 in additional time to the Inexperienced Bay Packers final Sunday, New York Jets coach Aaron Glenn struggled to elucidate to reporters why he elected to obtain the ball first in additional time. Glenn stated the Jets have been hoping to eat many of the 10-minute clock with their opening drive, rating a landing and put strain on the Packers to reply.
“It didn't occur for us the way in which that I deliberate," Glenn conceded.

Later that night time, Steichen additionally confronted a barrage of questions on why he selected to kick a game-tying area aim on the finish of the Colts’ lone additional time possession reasonably than going for it on 4th-and-8 deep in Kansas Metropolis territory. Steichen initially despatched his offense onto the sphere, solely to gesture to quarterback Daniel Jones to not snap the ball.
“Had a play referred to as, [but] needed to love the look to run it there,” Steichen stated. “And, if not, clearly we took the delay of recreation there and kicked the sphere aim to tie it.”

To Goings, probably the most egregious additional time coin flip determination this season was his favourite workforce’s. Having both not learn Goings’ examine or not agreed together with his conclusions, New Orleans Saints coach Kellen Moore — after profitable the toss — selected to kick the ball to Detroit in a 31-30 week 1 additional time loss to the Lions.
“They did the precise reverse of the technique I recommended,” Goings lamented. “That was fairly irritating to look at.”
