Ok Auburn is actually bad, but at least you're playing consistently at a high level. Don't look too far ahead to Iowa or you might fall for a trap game in Indiana (need you be reminded of the outcome last season).
4-0 with 2 wins over marquis programs, even if Auburn is having a down year. Most teams would love to scalp an SEC team that isn't Vanderbilt. Looking ahead at the schedule there's a top-5 matchup with Iowa looming.
Penn State beat Villanova this week, so not too tough of an opponent. It appears they didn't struggle with the same hangover that Auburn did from their matchup last week though. 
Played Villanova closer than they should have but Clifford is really coming into his own.  If he keeps playing well Penn State will be tough to topple and Clifford will be a Heisman contender.
Penn State is 4-0. Best win is over Auburn (3-1). Wisconsin win doesn't really mean as much as now they are 1-2. Could end up being a decent win if they get some wins. 
Wins over Auburn and Wisconsin now appear significantly less impressive after Auburn struggled against Georgia State and Wisconsin got obliterated by a decent but not spectacular Notre Dame after an impressive 4th quarter meltdown. Luckily for them OU sucks and struggled against WVU so they get to stay 5th...for now
