There wasn't a big shake-up in the rankings after Week 4 of the college football season, but only one matchup involved Top 25 teams.
That doesn't mean the week wasn't revealing.
With little margin for error in the college football season, teams must bring their best week in and week out. This past week, several teams played down to their competition. That could make for a rocky season for these overvalued teams.
No. 18 Michigan Wolverines
The Michigan Wolverines are 4-0, but they are coming off of two straight weeks of sloppy play.
Following a 28-24 win over Akron, Michigan needed a second-half comeback to pull out a 24-21 win over Connecticut.
There is something to be said about the ability to win ugly games, and Michigan has displayed that ability. But the Wolverines have a lot to work on before tackling the conference schedule.
It all starts with ball security. Michigan had four turnovers in each of the last two games. Quarterback Devin Gardner threw five interceptions in those two games.
And therein lies the problem. Unless Gardner starts proving he can beat teams through the air, Michigan is going to struggle on offense. As the schedule gets tougher, Michigan will not be able to turn those kinds of sloppy performances into wins.
No. 22 Notre Dame
It's fitting to move on to Notre Dame after discussing Michigan, as the Irish fell 41-30 to the Wolverines earlier in the year. That stands as their lone loss, but things are getting uglier by the week.
Notre Dame allowed the now-struggling Michigan offense to gain 460 yards.
At least the Irish played well on offense in that game, though. They mustered just 17 points this past week against the Spartans.
Notre Dame gained just 220 yards of offense and was actually outgained by offensively challenged Michigan State in that game.
Tommy Rees completed 14 of 34 passes against Michigan State, and he picked up just 142 yards on his completions.
Considering Rees offers very little production on the ground, that kind of passing is going to destroy Notre Dame's offense, and the defense is not good enough to carry this team through the season.
No. 9 Georgia
What a wild ride it's been for Georgia already this season. The Bulldogs opened up with a heartbreaking 38-35 loss to Clemson and then handled South Carolina 41-30.
But as the game against North Texas showed us, a troubling pattern is brewing in Georgia.
The offense played just fine in the 41-25 victory. The Bulldogs put up 641 yards of offense. Special teams, on the other hand, was atrocious.
North Texas returned a kickoff for a touchdown and blocked a punt in the end zone. The blocked punt actually tied the game at 21 in the third quarter.
Georgia is finding far too many ways to give up big plays. While the offense will be able to overcome much of that, this team is too sloppy to be ranked No. 9.
