The movie is a representation of the life of John Nash, a Nobel Laureate in Economics, for his developments in Game Theory. Most of you have probably heard about the notion of aNash Equilibrium which is, in summary, a situation in which no player wants to change his strategy, based on what the other players are doing. A Nash Equilibrium does not need to be a good nor a desirable outcome, just a best response of all players. In other words, if all players can stop the time and think: am I doing the best I can considering what everyone else did? and they all find that choosing another strategy will yield them worse results, then that sum of strategies is a Nash Equilibrium.
The idea is simple: if all players do what is best for themselves ignoring that other players will also do what is best for themselves, then they will get a negative outcome. If, in contrast, they consider what other players may be thinking before making a decision, they may prefer to choose another action.
The example is easy to understand and well explained but it is full of mistakes! It is strange that a biographical movie about one of the best mathematicians of the history makes so many mistakes in a crucial part of the movie.
The illustration of the movie can be represented as a Sequential Game. All the men move first and receive a first response from the approached women. Then, they move again and receive a new response from the women. The idea of Sequential Games is that if the men can anticipate by backward induction that they will be rejected by the brunettes in the second subgame, they prefer to approach them directly in the first subgame.
Although the concept is part of Game Theory (and one of the most interesting and useful topics), it is not what John Nash studied! In fact, he focused on Strategic Games, in which all players have to move simultaneously. In other words, the situation represented in the movie that implies a game with two rounds, should not be part of John Nash biographical movie.
This is what actually drives me crazy. In a Nash Equilibrium, all the players must be playing their best response, taking into account what the rest of the players are doing. Therefore, if there are 4 men and 5 women and we assume that the blond is the prettiest and the 4 brunettes are less desirable, then an outcome in which the 4 men approach the 4 brunettes is not a Nash Equilibrium! in fact, all the men would individually be willing to change their action and approach the blond woman (considering that nobody else has approached her). Actually, this game would have four Nash Equilibria. In each equilibrium, one different man finishes with the blond and the three others finish with the three most beautiful brunettes. It is straightforward to verify that this is actually a Nash Equilibrium, because in this case, nobody would be willing to change his action. If one of the men that approached a brunette decides to approach a blond, he will have a worse outcome because he will be rejected by the blond (that was with other guy) and will finish without any woman. In addition, nobody wants to change their woman for the remaining brunette, because she is not as pretty as the ones that they have already approached.
This may be a bit too technical, and it seems reasonable that the director did not include it in the movie. There are some games in which there is not a Nash Equilibrium in pure strategies. For example, in Rock Paper Scissors, if A did Rock and B Paper, it is not a Nash Equilibrium because A would prefer to change to Scissors. But this is not a Nash Equilibrium because B would prefer to change to Rock, and it continues infinitely. However, the situation in which both players randomize and play each action with probability 1/3 is a Mixed Strategy Nash Equilibrium, because if the other one is playing that strategy, my best response is to do it too. The four Nash Equilibria described in the previous section assume that players do not play symmetric actions (one goes with the blond woman and the other ones with the brunettes). However, we can think about a Mixed Strategy Nash Equilibrium in which the 4 men randomize their actions, and approach the blond woman with probability P and a brunette with probability 1-P. The computation of P is not complicated, but we would need to assume some Bernoulli Values in order to maximize their expected utility.
Real life John Nash would agree that Adam Smith theory was incomplete, but the mistake was different. The real John Nash would never claim that the best result come from everyone in the group doing what is best for himself and the group, but from everyone doing what is best for himself taking into consideration what the rest of the group has done.
Behind Door No. 2? Buffalo. He loved the idea of playing in a \u201Csuper football culture,\u201D where community and team are one and the same and the air just smells like football. He\u2019s seen all of the wild tailgate videos in those Orchard Park mud lots. One of his former teammates, Jordan Phillips, signed with the Bills for a second time and was blunt: it\u2019s just different in Western New York. And, oh. The Bills boast arguably the best player in the sport themselves in Josh Allen.
The problem here: taxes. Factor in the abomination that is NYS taxes and the money between what Buffalo and Miami was offering was not comparable. \u201CI feel like Buffalo should pay different taxes! It\u2019s crazy.\u201D (Editor\u2019s note: Amen.) Of course, it was not strictly about handing over hard-earned money to the government. If Edmonds was money hungry, he would\u2019ve signed with a team like the Houston Texans. The first-time free agent did not want to, as he says, \u201Cchase the bag\u201D like others. \u201CI could\u2019ve gone to Houston for the highest-paid contract,\u201D he says. \u201CBut guys get lost \u2014 quick. And once you get lost in this league, it\u2019s hard to get back out.\u201D
Money matters with his daughter, Avery, growing so, so fast but Edmonds knew it was wisest to go to a situation where he\u2019d be used the correct way. That\u2019s what would lead to both wins and a third contract which \u2014 as a NFL running back in this wretched economy \u2014 is almost unheard of.
Florida\u2019s palm trees, beaches and zero state income tax have made the Dolphins a destination since 1966, but anybody assuming Edmonds is another sucker heading south to perish would be wildly mistaken. The man seated right here in the same boardroom he put pen to paper on that contract did his homework. He phoned others who played for new head coach Mike McDaniel. The theme? He\u2019s brilliant. He\u2019s a cerebral play designer who both X\u2019s and O\u2019s his personnel into an open crease and grasps the big picture of how one play can set up another\u2026 and another\u2026 and another as if the game of football is more chess match than tug-of-war.
\u201CI like to think I am one of the smartest football players in the entire league,\u201D Edmonds says. \u201CEspecially at the running back position. So whether it\u2019s knowing my assignments, knowing what the defense is trying to do to us. Being able to pair with a coach who is intelligent in that same manner really stuck out to me. With the system of how they use running backs outside of the backfield, it was a match made in heaven.\u201D
Tyreek Hill has been peace-signing DBs into the Upside Down his entire career. No one strikes more fear in a defense. (Ask Sean McDermott.) He\u2019s worth every penny of his four-year, $120 million pact. Jaylen Waddle, a man who ran a 4.37 in high school, has superstar potential. All he did as a rookie was eclipse 100 catches and 1,000 yards. After signing Edmonds, the Dolphins added Raheem Mostert. You know, the burner who surfs with the sharks in the offseason and torches the Green Bay Packers for 220 yards and four touchdowns in an NFC Championship Game. (His back story is wild, too.) Mostert and Hill own the two fastest times ever recorded by NextGen Stats, which started tracking the speed of individual players eight years ago. Mostert\u2019s blistering on-field time of 23.09 MPH was narrowly edged out Hill\u2019s career-best of 23.24 MPH.
Tight end Mike Gesicki is a yeti in his own right at 6 foot 6, 247 pounds with a 41 \u00BD-inch vert, 4.5 speed and an 82-inch wingspan. He\u2019ll undoubtedly benefit from the tutelage of Jon Embree, one of the position\u2019s true tight end whisperers. It\u2019s still hard to believe San Francisco let one of the position\u2019s greatest teachers of all-time exit the building.
The arm\u2019s race didn\u2019t end there. The Dolphins signed Cedrick Wilson, who had 602 yards and six scores last season in Dallas. And traded for Sony Michel, who sparked a Patriots Super Bowl run in 2018. And drafted Erik Ezukanma in the fourth round. And recently signed vet Mohamed Sanu. And let\u2019s not sleep on Lynn Bowden Jr., profiled here. He\u2019ll return from injury. The offensive line, a sieve last season, will only improve with the arrival of Terron Armstead and Connor Williams.
The mad scientist mixing potions together to make this all work looks and sounds nothing like NFL head coaches of the last century. When Dolphins camp opened this week, McDaniel posed for a selfie with the local beat writers. He\u2019s a candid, calm, bespectacled scholar of a boss devoid of ego at the podium and that\u2019s a welcomed 180 for a team historically run by offensively challenged coaches. McDaniel\u2019s scheme is extremely \u201Cdetail-oriented,\u201D Edmonds explains, in how he can \u201Cwindow dress\u201D a play. In other words, Miami will make plays look the same in the run game when they\u2019re not the same at all. Blocking schemes are tweaked ever-so slightly. A guard. A tight end. A receiver. One microscopic change creates an entirely new angle within the zone scheme.
