Who did 5-or so-minute sports capsules on each of the 4 major networks? CBS I know had Pat Summerall, Phil Rizzuto and Win Elliot, NBC, Curt Gowdy, Joe Garagiola, and later Wally Robinson on weekends in the '80s, Mutual had Al Wester and Jack Gregson, and ABC pre-and-post split, Howard Cosell, Tom Harmon, Lou Boda and Don Chevrier. There may be some others I'm leaving out.
