1. All of the preseason top 8 teams are still unbeaten, and Alabama (at Arkansas) is the only team out of that group that isn't a double-digit favorite this week.If all are victorious, it will be only the second time that the preseason top 8 have gone undefeated into October. The first time was 1952, when the season opened on Sept. 27. Even then, one of the teams had a tie on the first weekend.
2. You'd think it would take Nick Saban more than three-and-a-half seasons in Tuscaloosa to equal any of Bear Bryant's accomplishments there, but he's now a win away from a fairly significant one. Going back to last season, Alabama has been ranked No. 1 in the last six AP polls. Believe it or not, that’s just one shy of the school record for consecutive weeks at No. 1, achieved by Bryant's teams in both 1979 and 1980.
3. Here are a few eye-popping numbers on Joe Paterno's tenure as Penn State head coach. Since he took over that job in 1966, there have been 876 head-coaching changes in major-college football. Twenty-two active head coaches in the FBS weren't even born then. And, in Penn State’s game against Kent State last Saturday, Beaver Stadium attendance during Paterno's time as head coach surpassed 23 million (23,098,439 to be exact). That's more than the population of Australia.
4. Even with an Irish head coach, Notre Dame hasn't been able to improve in the luck department this season. After back-to-back tough losses to Michigan and Michigan State, ND now has eight straight defeats by seven points or fewer - the longest active streak in the nation. That's one more than Iowa, which had some tough luck of its own last weekend at Arizona.
5. A Michigan win Saturday against Bowling Green would make the Wolverines 4-0 for the second straight season. Even before recently falling on rough times, back-to-back 4-0 starts wasn't exactly a common occurrence in Ann Arbor. The last time Michigan started consecutive seasons at 4-0 was 1995-97. Before that it was 1985-86, and then 1976-78 prior to that. In other words, it happens about once a decade.
