From 1960 to 1966, the AFL and NFL drafts were separate and each league competed for players, a major factor in their merger. During the three years of the common draft, teams from both leagues were combined in a single ranking to determine the order of the draft. The team with the worst record in either league the previous year picked first, the next-worst team second, and so on, with the exception that the loser of the previous year's World Championship Game picked second to last, and the reigning World Champion picked last. As is the case today, any team's draft order could be affected by trades. When the two leagues formally merged for the 1970 season, the "common draft" became the modern NFL draft.
