Swarmerin-fighter

In-fighters/swarmers (sometimes called "pressure fighters") attempt to stay close to an opponent, throwing intense flurries and combinations of hooks and uppercuts. A successful in-fighter often needs a good "chin" because swarming usually involves being hit with many jabs before they can maneuver inside where they are more effective. In-fighters operate best at close range because they are generally shorter and have less reach than their opponents and thus are more effective at a short distance where the longer arms of their opponents make punching awkward. However, several fighters tall for their division have been relatively adept at in-fighting as well as out-fighting. The essence of a swarmer is non-stop aggression. Many short in-fighters utilize their stature to their advantage, employing a bob-and-weave defense by bending at the waist to slip underneath or to the sides of incoming punches. Unlike blocking, causing an opponent to miss a punch disrupts his balance, permits forward movement past the opponent's extended arm and keeps the hands free to counter. A distinct advantage that in-fighters have is when throwing uppercuts where they can channel their entire bodyweight behind the punch; Mike Tyson was famous for throwing devastating uppercuts. Julio Cesar Chavez was known for his hard "chin", punching power, body attack and the stalking of his opponents. Some in-fighters, like Mike Tyson, have been known for being notoriously hard to hit. The key to a swarmer is aggression, endurance, chin, and bobbing-and-weaving. Notable in-fighters include J

e Frazier, Mike Tyson (in his early career), Rocky Marciano, Jack Dempsey,[28] Wayne McCullough, Amir Khan, Harry Greb,[29][30] David Tua, Ricky Hatton and Julio Cesar Chavez. Rocky Marciano (born Rocco Francis Marchegiano; September 1, 1923 August 31, 1969) was an American professional boxer and the World Heavyweight Champion from September 23, 1952, to April 27, 1956. Marciano is the only champion to hold the heavyweight title and go untied and undefeated throughout his career. Marciano defended his title six times. Marciano was born and raised in Brockton, Massachusetts to Pierino Marchegiano and Pasqualina Picciuto. Both of his parents were immigrants from Italy: his father was from Ripa Teatina, Abruzzo, while his mother was from San Bartolomeo in Galdo, Campania. Rocky had three sistersAlice, Concetta and Elizabethand a brotherPeter whom they called Sonny. When he was about eighteen months old, he got pneumonia, from which he almost died. In his youth, he played baseball with his brother Peter a.k.a Sonny and David Rooslet (a neighborhood friend of Marciano's), worked out on homemade weightlifting equipment (later in his life, Marciano was also a client of Charles Atlas)[1] and used a stuffed mail bag that hung from a tree in his back yard as a heavy bag. He attended Brockton High School, where he played both baseball and football. However, he was cut from the school baseball team because he had joined a church league, violating a school rule forbidding players from joining other teams. He dropped out of school after finishing tenth grade.
