Super Bowl '17 point spreads

[RolandoRoomes 33]

I have never bet in my life, true story.

 

 

Looking at the spreads, I need some help understanding.

 

 

So what do these mean

 

Patriots -21 1/2

Patriots -14 1/2

 

Patriots +14 1/2

 

 

 

 

I want to place a bet that the Pat's win by 17 or more and not sure what to do

those must be alternate spreads your book is offering - the 2 at the will pay you nice plus money...the spread where they are getting the 14.5 would be INCREDIBLY HIGH JUICE...
