Here are a couple of links that show how well each team beats their opponents when they are:
Home/Favs
Home/Dogs
Vis/Favs
Vis/Dogs
If you look at the last column (RL +/-) in each table is shows how much that team has beaten the RL margin by in the given scenario (i.e. as a Home/Fav, Home/Dog, etc...) for the season.
The MOV column is the margin of victory in all games they've played this season.
I thought this info might be useful info for you if you're considering RL plays.
