If all the favorites win, here's how the BCS bowls will play out:

Rose: Texas vs. USC*
Fiesta: Notre Dame vs. Ohio State
Sugar: LSU vs. West Virginia*
Orange: Virginia Tech vs. Penn State*
*--already clinched BCS bowl berths

Now consider a scenario in which Texas and USC lose. We're projecting that Texas would probably drop out of the top two but remain an automatic at-large team by staying in the top four. There is debate whether USC, especially with a close loss to UCLA, would drop out of the top two. Like Nebraska in 2001 and Oklahoma in 2003, the Trojans could lose their final game and still play for the national championship.

Rose: USC vs. Penn State
Fiesta: Colorado vs. West Virginia
Sugar: LSU vs. Texas
Orange: Notre Dame vs. Virginia Tech

If USC drops below No. 2, look for it to end up this way:

Rose: LSU vs. Penn State
Fiesta: Colorado vs. USC
Sugar: Notre Dame vs. West Virginia
Orange: Texas vs. Virginia Tech

Now, let's say all the favorites lose -- USC, Texas, Virginia Tech and LSU. Here's the lineup:

Rose: Penn State vs. USC
Fiesta: Colorado vs. West Virginia
Sugar: Georgia vs. Texas
Orange: Notre Dame vs. Florida State
