Interesting trend in Vegas

At the Wynn sports book, TCU opened as a 9.5 point favorite over the Hogs on Sunday. By today it was down to TCU -8.

I’m not a gambler. What exactly does that mean? Is it good or bad?

It means that the site set the points and enough money has already come in on the Hogs to cover that the site adjusted the spread they were offering. Means enough people beleive that the Hogs would cover that it pushed the spread down
