Legendary former Georgetown men’s basketball coach John Thompson Jr. has been a fixture on D.C. sports radio for more than a decade, but on Friday “Big John” announced his run is coming to an end.

During Friday’s broadcast of ESPN 980’s weekday radio program “The John Thompson Show,” the 70-year-old Washingtonian announced he is ending the program in February after 13 years on the air.
