There used to be an “All-Star” game where the dreaftes of the previous year met pro footbal’s champion. They won several games, including beating Vince Lombardi’s Green Bay Packers team once.
And this was a team that hadn’t played together all season.
Yes and the pros used to put a half-hearted effort into it as the coaches did not want their players to get injured in a meaningless charity exhibition game. The Pros usually played at 1/2 speed and let the subs play alot. If those NFL teams really played it serious the All-stars never would have won or even gotten close. Nor would the collegians want to play in a game where they got their heads kicked in. I’ve read a few books from NFL players from that Era who talked about this game and said it was more for fun if anything.
