I call this approach the Duhhh approach due to its simplicity 
The Duhhh approach focuses on teams that meet twice in the same season. If a road team beats a home team by a double digit margin, the road team is likely to do the same when they play at home.
Three classic examples come to mind :
1) Indianapolis and Houston :
Indy wins on the road by a 18 point margin. Indy wins at home again by 2 touchdowns.
2) Seattle and Arizona :
Seattle wins on the road by a 14 point margin. Seattle wins again at home by a 25 point margin.
3) Cincinnati and Baltimore :
Cincy wins on the road by a 12 point margin. Cincy is as we speak beating Baltimore by a 27 point margin going into the 4th quarter.
Not too many games out there that meet the Duhhh criterias but when you see one, it is worth taking a very close look.
