EAGLES v Bears

Bears are home and favorites. Point is spread is 3 pts.

Money line is +150/-170

Couple questions:

Is this a typical money line for a 3 pt spread?

What is the analysis/matchups that make the Bears favorites? I was thinking maybe Bears by 1 since they're the home team.

Disclaimer: I'm an EAGLES fan and I'm horrible at handicapping football games.

DonDiego doesn't know what computation the sports books use, but some online sites provide charts indicating the relationship.

sportility.net suggests a 3-pt spread should be:
-160/+140 moneyline

PredictEm.com suggests a 3-pt spread should be:
-155/+135 moneyline

It seems getting +150 on the dog with a 3-pt spread is a good bet.

Speculation: Maybe the calculated point-spread is like -2.77, and they've shaded the money-line to capture the difference. [If this is so, grab the +150 before the line goes to -2.5.]
Speculation: Maybe the charts poor old DonDiego cited are crap. [If this is so, . . . DonDiego, as usual, disavows any responsibility for losses incurred after reading anything which DonDiego has posted.

*****EDITED TO ADD*****
DonDiego's gambling library contains a copy of Football Betting by Jim Feist and Kelso Sturgeon which presents a table similar to those above indicating a 3-pt spread should have:
a -150/+130 moneyline.

And a 4-pt spread should have:
a -170/+150 moneyline.

DonDiego just looked at an online book, sportsbook.ag posting:
__a -3 1/2 [ev] ; +3 1/2 [-120] point-spread
__a -170/+150 mopneyline

The moneyline has been rising; i.e. money is coming in on Chicago.
vegasinsider.com indicates the line has risen from as low as -2 at Westgate up to as high as -3 1/2 at Southpoint now.

Odds on DonDiego's beloved Eagles may go up more !

Consider what the actual animals would do in a confrontation. The bear would tear the eagle apart and eat it. Bet heavily on the bear.

Actually one would think that after last weeks game, where Philadelphia looked good and Chicago looked bad, that the Eagles would be the choice, plus you would be getting the points. I agree with you though, and feel the Bears will win.

I will be there and cheering on the Bears........weather looks to be great for MNF!

Take the bears.

Whatever initial odds the sports book selects eventually move dependent on the money bet; the sports book doesn't usually want to bet, they'd prefer the same amount bet on both sides and to just keep the vigorish.

The present odds at Wynn are:
Chicago -3
ML Chi-170;Phi+155

For those sports bettors interested vegasinsider.com presents the history of the line movements at many of the more well known Nevada casinos.

n.b. It seems DonDiego's speculation in his earlier post is correct; the history at the William Hill books shows the money line oscillating yesterday during the afternoon/evening while the spread remains at -3.

So a Bear fan bets $170 to win $100 is the Bears win the game.
An Eagle fan bets $100 to win $155 if the Eagles win the game.

It looks like they are trying to get more money bet on the Eagles, to even the bets.

Just so, but it's not because of any preconceived preference at the Sportsbook.

The betting public has a notion that the Bears are going to win, therefore the money line has to offer "the public" an enticement to bet the Eagles.
So, fr'instance at the William Hill sportsbooks on Tuesday morning the line went up at -155/+135.

However, during the week the money flows, . . . sometimes onto the Eagles and sometimes onto the Bears. To keep both sides close to even the book the bookie will change the odds a bit.
Early money went onto the Bears, so at 11:14 Tuesday the line went to -165/+145
__ at 11:28 to -170/+150, . . . still trying to get some money on the Eagles
__ at 22:17 back to -165/+145, . . . to attract money onto the Bears
__ at 22:20 back to -170/+150, . . . in 3 minutes somebody bet enough on the Bears to move the odds back to what they'd been at 11:28 in the morning.

Las Vegas is a great place to bet because at any given minute, the odds can be different at different sports books; if someone can keep track he can bet wherever he gets the better odds.
However, one person cannot be in two or more places at once; this is why cell phones are prohibited in the sportsbooks.
