Week 3 in the NFL is an interesting week, because it is the first week after which the first teams are basically eliminated from playoff contention. Only three times since 1990 (‘92 Chargers, ‘95 Lions, ‘98 Bills) has a team made the playoffs after starting 0-3. Since realignment in 2002, not one of the 78 teams that started the season 0-3 made the playoffs, which means the 0-3 teams (Raiders, Texans, Cardinals) can start doing mock drafts.
The table below shows what the playoff odds have looked like over the last 16 seasons by W/L after the third game of the season.
