The AFL also forced the NFL to expand: Dallas cowboys built up against the Dallas texans of the AFL. Texans moved to Kansas to become chiefs in 1963; The Minnesota vikings Madden 18 Coins are the NFL's ball team out of AFL to Max Winter; The Atlanta falcons offer Ranki Smith to dissuade him from buying the AFL Miami dolphin.

The constant price competition between the NFL and AFL is almost beyond the spirit of sport. In 1966, the two leagues agreed to merge in 1970. Ten AFL teams have joined the existing NFL teams to form the NFL's American Football Conference. The other 13 NFL teams became the National Football Conference.
