Does anyone else like to calculate these? I find it interesting to figure based on the current ML's, divisional champ. odds and super bowl odds. I try to use the "no vig" lines.
Here are my figure for the Chicago Bears, based mainly on Matchbook no-vig lines with an eye at Pinny's no-vig as well.
Assumptions:
ML vs. Seattle = -410 (1.2349)
Divisional champ. = +216
Super Bowl = +920
These give us an implied NFC line of +156 and then, if won, a Super Bowl line of +260.
+156 is vs. he unknown of GB or ATL. So then I figured GB's implied odds:
ML vs. ATL = +122
Divisional champ = +260
Super Bowl = +720
This gives us an implied NFC line of -162. Now you have to figure a 20% chance of facing Seattle and 80% chance of facing Chicago. I'm not going to go that deep but I'll say it should be around -140 vs. Chi and -280 at Sea. I think that works out about right.
Getting back to +156, we see +140 vs. GB and then average that back to around +175 at ATL.
So barring anything unusual, Chicago should be:
+130/-150 vs. GB (call it GB -2.5-120 or -3+100)
+165/-190 vs. ATL (call it ATL -3.5-110)
Does this look about right? Should Chicago be nearly 3 point home dogs to GB?
