Why the lines move so much?

[Scorpion]

Why the lines move so much in college football this year?

A game may open -10
Then it moves to -8
Then it moves to -9
Then it moves again to -8
Then -9.5, and so on

This happens for too many games this year, do sportsbooks own don best and other line services?

Don't trust any of those bet % and line move movements that sites like covers, pregame, donbest, sportsinsights, sbrodds spit out. All these sites' major revenue is from player losses to sportsbooks (affiliate commission)

Improved modeling among several major players.

Limits are relatively low throughout most of the week and people have different opinions.

And how is that different from past years? Nothing new really.
