Early life and education

Born in Chicago, Illinois, McMahon attended De La Salle Institute where he developed as a multi-sport athlete alongside contemporaries from Cook County, Illinois high school circuits. He matriculated at University of Notre Dame and played under coach John Jordan during the mid-1950s, competing in the Big Ten Conference era collegiate schedule and participating in matchups against programs like University of Kentucky, University of Kansas, University of North Carolina, and University of California, Los Angeles. At Notre Dame he earned recognition that drew attention from National Basketball Association scouts, leading to selection in the 1957 NBA Draft.

Playing career

McMahon entered the professional ranks with the Cincinnati Royals in the late 1950s, joining teammates such as Oscar Robertson during Robertson's early career. He also spent time with the St. Louis Hawks, appearing in matchups against perennial contenders like the Boston Celtics, Los Angeles Lakers, and Philadelphia Warriors. Playing as a guard, McMahon competed in seasons defined by figures including Bill Russell, Wilt Chamberlain, Jerry West, and Bob Pettit. His playing tenure occurred during the transitional period when the NBA faced competition from rival organizations and the sport expanded into new markets such as San Francisco and St. Louis. Injuries and roster shifts curtailed his on-court longevity, prompting an early move into coaching and player development with connections to franchises like the Chicago Zephyrs.

Coaching career

McMahon's coaching career began with the Chicago Zephyrs, where he joined the coaching ranks amid organizational realignments that included relocation and rebranding efforts linking to the Baltimore Bullets and later Washington Bullets. He served as head coach of the Cincinnati Royals during the era when the franchise featured stars such as Oscar Robertson and contended with rivals including the Boston Celtics dynasty led by Bill Russell and Tom Heinsohn. Later, as head coach of the Kansas City-Omaha Kings—the relocated incarnation of the Cincinnati Royals—McMahon navigated franchise transitions involving ownership and arena negotiations tied to cities like Kansas City, Missouri and Omaha, Nebraska. He subsequently coached the Houston Rockets during the early 1970s, overseeing rosters containing players who competed against personnel from the Milwaukee Bucks, New York Knicks, and Phoenix Suns. McMahon's coaching style reflected influences from contemporaries such as Red Auerbach, Alex Hannum, and Red Holzman, and his tactical decisions were shaped by matchup strategies against teams coached by figures like Bill Sharman and Larry Brown.

Executive and scouting roles

After coaching, McMahon transitioned into executive and scouting roles, contributing to talent evaluation for franchises including the New York Knicks, Milwaukee Bucks, and Boston Celtics. In these capacities he scouted prospects coming out of programs such as University of North Carolina, University of Kentucky, University of Kansas, Indiana University Bloomington, and Duke University, and he assessed international talent amid growing global recruitment influenced by events like the 1992 Summer Olympics basketball tournament. McMahon's front-office work involved collaboration with executives such as Red Holzman (in personnel contexts), Pat Riley (in organizational trend observations), and Jerry Sloan (regarding player evaluation philosophies). His scouting reports informed draft decisions during draft classes featuring athletes like Kareem Abdul-Jabbar, Magic Johnson, Larry Bird, and later generations including Michael Jordan and Hakeem Olajuwon. McMahon also contributed to player development programs that interfaced with scouting departments of the NBA Development League and international clubs.

Personal life and legacy

McMahon maintained personal ties to the Chicago area and later relocated seasonally to Cape Cod, Massachusetts, where he passed away in 2013. He was remembered by peers and organizations across the NBA and ABA communities for his multidisciplinary contributions—spanning player, coach, and executive roles—and for mentorship influencing coaches and scouts who worked with franchises such as the Celtics, Knicks, and Bucks. Tributes referenced his connections to notable basketball figures including Oscar Robertson, Bob Cousy, Bill Russell, and Red Auerbach, situating McMahon within the mid-20th-century evolution of professional basketball.
