there used to have a preseason game every year, The Chicago Charities College All-Star Game, NLF champs vs College All Stars, 1934 - 1976. I didn't know it lasted that long. But the overall series was NFL 30–9–2. But that was a different time, it would never be close now, especially if you are talking NFL champs vs College All Stars. Worse NFL team vs College All Stars, it may be close for the first half, but i still don't think it would be close..
