Since the 1970 merger, there’s been 17 Steelers to go for 150+ receiving yards in a game. Most on the list are household fans the casual fan would recognize. Antonio Brown, Lynn Swann, Hines Ward, you get the idea.
Then there’s Joey Clinkscales. It was 1987 and his time to shine.
Perhaps I’m stretching the limits of “next man up” here. Clinkscales was part of the 1987 replacement players as most stars and many starters were on strike. In that sense, essentially everyone he took the field with was “next man up.” Or in some cases,”next man off the street.
