After watching the Dolphins get blown out in their first two games of the season, it looks like oddsmakers are expecting more of the same this week when Miami travels to Dallas. 

In the early odds for Week 3, the Dolphins have opened as a 20.5-point underdog to the Cowboys, which is mostly notable because it marks the first time in 32 years that the Cowboys have been favored by at least that many points. 

That's right, not even the great Cowboys teams of the 1990s were ever favored by 20 or more points. From 1992 to 1995 -- when the Cowboys won three Super Bowls in four years -- the most Dallas was ever favored by in a game was 18 points.
