Feinstein's career at The Washington Post began in 1977, but it had nothing to do with sports at first. He was a night police reporter, but he "soon distinguished himself on the sports beat," according to the outlet's obituary. 

"He covered a wide range of sports and developed a talent for deep sourcing that fed personality-driven and dramatic narratives about athletes, coaches and management," the obituary continued. 

While working for The Washington Post, Feinstein was also doing work for ESPN, NPR and the Gold Channel. He also had shows on SiriusXM. 

Feinstein also wrote more than 40 books, including the bestselling basketball book of all-time, "Season on the Brink," which debuted in 1986 after he took a full year off from his Washington Post gig to follow the 1985 Indiana Hoosiers and their polarizing head coach, Bob Knight.
