SBNation Reacts: Examining all of the conference battles halfway through the season

SBNation reacts is back this week, taking the pulse of each conference at the midway point of the season. After a massive week of college football, we had some serious changes in these conference races and the college football playoff picture.

We’ll start in the Pac-12, where Utah made things very interesting by beating USC last week. We’ll get another part of the picture this week as UCLA takes on Oregon. Are the Bruins for real? We’re about to find out.

On to the SEC. Tennessee sprung the upset on Alabama last week, putting themselves on a collision course with Georgia for a de facto East championship game.
