The AFC East rival Miami Dolphins and New York Jets are on track to become the first pair of 20-point underdogs in the same week since 1987.
ESPN's David Purdhum reported the last time there were two underdogs of that size was Week 5 of the 1987 NFL season, when the Philadelphia Eagles (+21) visited the Dallas Cowboys and the Atlanta Falcons (+23) hosted the San Francisco 49ers.
Neither the Cowboys nor the Niners covered the spread.
As of Tuesday afternoon, the New England Patriots were 22.5-point favorites over the Jets, while the Cowboys were 21.
