I've been continuing to visit the NFL way back machine on YouTube.
I found the last of the Chicago Bears replacement games from 1987, versus New Orleans. I had never known that Sean Payton (now the Saints head coach) was a replacement QB for Chicago. He was pretty awful, sealed the game for New Orleans with a late interception.
Some "highlights"...
The full game for the football starved or interested in the history of the game...
You know, the best head coaches are usually mediocre (at best) players. That seems to be a constant across all sports.
