George Karlaftis Bio
George Matthew Karlaftis III is a Greek professional American football defensive end for the Kansas City Chiefs of the National Football League (NFL). Born in Athens, Greece, he relocated to the United States as a teenager and went on to star at Purdue University, where he earned multiple All-Big Ten honors and first-team All-American recognition. Drafted in the first round of the 2022 NFL Draft, Karlaftis quickly became a regular starter and has already helped Kansas City win back-to-back Super Bowls. Standing 6 feet 4 inches tall and weighing about 263 pounds, he is regarded as one of the league’s promising young pass rushers.
Early Life and Background
George Matthew Karlaftis III was born on 3 April 2001 in Athens, Greece. His father, Mathiós “Matthew” Karlaftis, grew up as an all-around athlete in Greece and later earned a degree in civil engineering at the University of Miami before pursuing a doctorate at Purdue University. His mother, Amy, who had grown up near Purdue in West Lafayette, Indiana, met Matthew while she was a freshman. After marrying, the couple settled in Athens, where Amy spoke English to their four children at home while raising them in Greek culture.
Matthew died of a heart attack in 2014 on the island of Kos, where he was scheduled to deliver a speech at an engineering conference. Following his father’s death, Amy and her children moved back to West Lafayette, and George enrolled at West Lafayette High School. In his early years in Athens, he had played water polo as a goalkeeper in the youth ranks of Panathinaikos, the Greek club he continues to support.
At West Lafayette High School, Karlaftis quickly made his mark on the football team, recording 41 sacks over his high school career. He also competed in track and field, winning back-to-back state championships in shot put. He played in the 2019 U.S. Army All-American Game, where he was named the Defensive Player of the Year. He graduated early and enrolled at Purdue in January 2019.
Path to American Football
Karlaftis arrived at Purdue as a highly regarded defensive end prospect and immediately earned a starting role. As a true freshman in 2019, he started all 12 games, recording 54 tackles and 7.5 sacks on his way to second-team All-Big Ten honors. That production announced him as one of the conference’s most disruptive young defenders.
His sophomore season in 2020 was limited to three games after he tested positive for COVID-19, finishing the year with four tackles and two sacks. Despite the shortened campaign, he again earned second-team All-Big Ten recognition, reinforcing his reputation as a relentless pass rusher. In 2021, Karlaftis elevated his game, earning first-team All-Big Ten honors and first-team All-American recognition while recording 4.5 sacks. Following that season, he declared for the 2022 NFL Draft, where the Kansas City Chiefs selected him in the first round with the 30th overall pick.
