So far this season, the Raiders have been more comfortable in the underdog role. Both of their wins this season, they were underdogs (though just by one point). Their loss at home against the Falcons, they were 4.5-point favorites. Now they head to Baltimore to face the 3-0 Ravens who are 3.5-point favorites to handle their business.
Part of the reason for the underdog status of the team so far this season is they've all been road trips 10am Pacific start times. West coast teams making the trip east puts them at a statistical disadvantage. We'll see if the Raiders can buck the trend of the East Coast swing as well while continuing their winning underdog ways.
