Top 25 picks

Division I-A and I-AA football no longer exist.

In an effort to make the schools formerly known as I-AA feel less like second-class institutions, the NCAA has divided Division I football into the Football Bowl Subdivision (I-A, which uses bowl games as its postseason) and the Football Championship Subdivision (I-AA, which uses a playoff and actually crowns an NCAA champion in the postseason).

So when Louisville whipped Murray State by 63 points, remember the Cardinals clobbed an FCS team.

As for the competitive games in this opening weekend of college football, No. 12 California hosts No. 15 Tennessee. The picks:
