That was quite a shakeup in Week 6 of college football.
Some top teams such as LSU lost some ground, and others were just knocked out of the AP Top 25.
No. 1 Alabama stayed at 5-0 on an early bye week, and No. 2 Oregon fought off pesky Washington in a very offensive game.
But the season is just warming up and the Top 25 may be up for grabs for teams outside of the rankings.
Consider it a friendly reminder to all teams in the Top 25 that they have to stay on their toes in the coming weeks.
These are the schools that may surge into the Top 25 in the second half of the season.
Former No. 23 Washington is coming off a 52-21 loss to No. 2-ranked Oregon in a realization that it can battle for a spot in the Top 25.
Washington was able to upset No. 8 Stanford 17-13 only a couple of weeks ago with stellar offensive play and a better defensive game.
But even with stellar offense and defense, the Huskies will have to bring their best as they take on No. 11 USC in their upcoming game.
No time to rest or take a break, Washington has a legitimate chance to surge into the Top 25 with a crucial win.
Former No. 24 was about to go 6-0 for the first time in 50 years, and it was a dream on the mind of every Wildcat fan.
But then Penn State decided to play the fourth quarter and score 22 straight points to beat Northwestern, 39-28.
As heartbreaking as that loss was, even more so was Northwestern's fall from the Top 25.
But the Wildcats can claw their way back into the rankings with a strong finish over the next eight weeks.
Former No. 15 TCU saw its winning streak of 12 come to an end at the hands of Iowa State, 37-23.
Worse, TCU is no longer in the Top 25.
But one loss shouldn't deter the Horned Frogs from fighting their way back into the Top 25. If anything this team is built to make a comeback.
Regardless, look for TCU to regain a position in the Top 25.
Former No. 21 Nebraska lost its footing with a loss to Ohio State, 63-38.
Defense was much of the story in Nebraska's loss that saw the Huskers get knocked out of the Top 25.
Nebraska coach Bo Pelini said that his team can't afford another mistake. (via Fox News):
As I just told the football team, we need to win out, (Winning the rest is) the only way we can guarantee getting ourselves to Indianapolis.
Look for Nebraska to bounce back, and even if the Huskers don't make it to a Big Ten championship game, they will crack the Top 25 once again.
