Money line with a spread

[RedeemerKing]

I know how the money line works and how the point spread works. My question is why is there both sometimes? Like tonight the Broncos were -3 but +110 on Wager7. I didnt check out other sites to see other lines. Would all sites incorporate this money line for the game or would it depend on the action that specific sportsbook received. When the situations do come up do they allow for a good hedge opportunity? So, why are there sometimes a money line and point spread and can the bettor take advantage of this in anyway?


Thanks
