1.Upset special: With Southern Cal falling out of the No. 1 spot with a loss to Oregon State on Thursday, No. 2 Oklahoma looks poised to become the leader of the pack. This might be a perfect time for TCU to sneak in the upset.
2.Offensive explosion: Buffalo's Drew Willy and Central Michigan's Dan LeFevour are two of the most prolific quarterbacks in the MAC and when they get together this weekend, both defenses better be on high alert.
3.Catch more, Passmore: If you don't know the name Darius Passmore, you will by the second half of Marshall's game against West Virginia. Passmore leads all receivers in receiving yards per game and should have a field day against WVU's 86th-ranked pass defense.
4.Dominance of the Pac-10: The Mountain West and the WAC have a chance to continue to kick the Pac-10 while it's down. Fresno State will attempt only its second win in the eight times it's met UCLA, and Colorado State will look to extend the Mountain West's streak over the Pac-10 to 6-0 with a win at Cal.
5.Crazy finish: Arkansas State and Memphis have had some crazy finishes the last two seasons and considering the way Memphis' season is going, it wouldn't be surprising to see another one. The Tigers' last two loses have been by a touchdown or fewer.
6.Notre Dame, good or bad?: After its first loss of the season last week, there's no telling how the Irish will play this week when it hosts Purdue. This is one of many winnable games on their schedule, but you never know when thoughts of last year could creep in.
7.Moving on: Ball State played with great emotion after the loss of receiver Dante Love, but a week after his injury, how will the Cardinals respond against Kent State? The Cardinals are already in the midst of one of the best starts in school history and that should continue if they don't get in their own way.
8.Six more touchdowns: Tulsa quarterback David Johnson could throw six more touchdowns when the Golden Hurricane play FCS opponent Central Arkansas. Smith has thrown six touchdowns in each of the last two games -- a C-USA record.
9.Movin' on up: BYU could find itself in the top 10 this week even though it's idle. After Southern Cal's loss to Oregon State, every team below the Trojans figures to move up until the Trojans find their spot. A couple more upsets, which is possible, could put the Cougars in the top 10 for the first time since Dec. 2, 2001.
10.Success story: UNLV has burst onto the scene as a one-team BCS wrecking crew, but what happens when it drops back to non-BCS earth? We'll see this weekend when it meets in-state rival Nevada. Nevada has won each of the last three meetings, but might still be smarting from a thrashing at Missouri two weeks ago.
