Let's say that bizzare accident didn't happen and the trade goes smothly and packers keep more pick they surrendered in real life, besides rams will be doomed to mediocrity will packers capitalize that? Let's remeber that By 1978, Green Bay did contend for a playoff spot. They finished tied with the Vikes for the division title. If they had Manning, they probably win the division that year, and he may have made a big difference for them in 1979 and in the next few years after that because the Central Division was pretty weak back then, and didn't have an elite team until Chicago emerged in 1984.
Might have Manning get good numbers with better organization and with Bart Startt later as coach maybe getting deep into playoff before the Bearevolution of Ditka happen in chicago?
How Might affect Manning Family? by 1974 neither of any manning bros have born yet...
