The New York Jets and Green Bay Packers have a 23 percent chance of making football history — the first Super Bowl between a pair of No. 6 seeds. Since the National Football League’s postseason expanded to 12 teams in 1990, the 2005 Pittsburgh Steelers are the only team to reach the Super Bowl as the final seed in its conference, a feat that requires three straight playoff wins on the road. The odds against a Super Bowl between the Jets and Packers at the start of the playoffs were 138 to 1, a 0.72 percent chance, said RJ Bell, president of Las Vegas-based handicapping information website Pregame.com. Those odds are slightly less than 3-1 now that both teams are in their conference championship games. — Bloomberg
