Since 1991, NFL teams that win back-to-back games straight up as an underdog are just 40-68-2 Against The Spread in their next game if they are on the road and not getting more than 7 points.  In fact they are  19-48-1 ATS if visiting a non-divisional opponent.  What is the psychology driving this trend? Simply put: such teams are less motivated while their opponent is on high alert!

Home underdogs are 173-128-9 ATS if they won straight up as an underdog the previous week.   They feel confident!
