In the 80's, it went to 70 players after the first game, 60 players after the second game, 50 players after the third game, and finally, 45 players after the fourth game. Things were more exciting back then. There was no practice squad and no 53-man roster. Training camp began in early July. The first week of the season was on Labor Day weekend. The Super Bowl was always in January. Players were tougher and less injury prone. The teams have it too good nowadays.
