Interesting info - thanks for sharing.
This week was a bit of an odd one. I remember all but one of the morning games were less that 2 points spreads. I think one was 8.
The number of spread mattering games this year does seem quite low. I tend to lean towards the money line when picking the underdog. I'll also often times place incremental bets on higher spreads since when a favorite covers they'll often win by a large margin.
For example, KC/TEX game Sunday night I took KC -3.5 (-110), KC -7.5 (+165), KC -10.5 (+260). I lost the -10.5 in the last minutes but almost cashed them all. I hedged with TEX +12.5 part way though so it came out nicely. I won 3/4 bets with 2 of those 3 @ +150 or better.
Anyone interested, check out the Behind the Bets Podcast on ESPN radio. This time of year they have the head book maker from Boyd Gaming on and he shares a lot of insight into how lines are made. The biggest things I've learned is that books DON'T set lines where they think the game will end up. They set them where they think 1/2 the money will land on each side. Hacks like me help out the pros by always taking the "sexy" flashy picks, leaving a lot of value on sides that nobody wants. In general, the public loves to bet on teams like the Cowboys, Packer, Steelers, etc. It's not as much fun throwing down money hoping CLE only gets killed by 12 points.
