College football: All the numbers to know after a chaotic Week 7

After a rather strange first half to the college football season, let the numbers do the talking. Some good, others bad, still others ugly.

Eight unbeaten teams are left. This time last season, there were 11. Two years ago, there were 14.

Seven top-25 teams lost to unranked opponents over the weekend. Meanwhile, Alabama won for the 72nd consecutive time against unranked opposition.

Only three of the unbeatens – Alabama, Penn State and Wisconsin – were ranked in the top 14 in the preseason polls. TCU was not in the top-25. UCF did not receive a single vote.

Three — Miami, South Florida and UCF — are from the state of Florida.

Miami leads the ACC Coastal division. In 12 years in the league, the Hurricanes with all their tradition have never played in the ACC championship game.

South Florida has scored at least 30 points in 23 consecutive games, matching Oregon circa 2011-12 as the only teams to do that since at least 1936. The Bulls also lead the nation with an 18-5 turnover margin.

UCF leads the nation in scoring at 50.6 points a game and is 5-0 for the first time in 29 years.  Two years ago, the Knights were 0-12.

Alabama has trailed for two minutes and 26 seconds out of 360 minutes in six games

The Tide have scored 100 points in first quarters this season. They has given up 71 in all four quarters.

Penn State has outscored the opposition 76-0 in the first quarter. That might change soon. The Nittany Lions’ next three opponents – Michigan, Ohio State and Michigan State – are a combined 14-3, with Ohio State and Michigan State on the road.

Since 2009, Kansas basketball has won nine Big 12 conference championships. Kansas football has won five Big 12 games.

Florida State had a total of two league defeats in its first nine seasons in the ACC, starting in 1992.  The Seminoles had two in their first three conference games this season.

BYU has had more than six losses in a season only twice in the past 46 years. The 2017 Cougars already stand at six defeats.

Ten years ago, Illinois went to the Rose Bowl. The Illini are 19-56 in Big Ten games since.

Washington and Washington State were both 6-0 before the past weekend, averaging between them 82.7 points a game. Both lost. They combined to score 10 at Arizona State and California.

Midway through the 2016 season, Baylor had won 32 of its previous 39 games. The Bears are 1-12 since.

Notre Dame’s five wins have come by an average of 28 points – over Michigan State and four other teams with a combined record of 9-19. Its lone defeat to Georgia was by one point.

Louisville has gone from a top-20 team with the returning Heisman winner to tied for last place in the ACC Atlantic division.

Tennessee visits Alabama this week. The Volunteers have scored 29 points in three SEC games. The Tide has allowed 31 in four.

Indiana has lost in overtime to Michigan two of the past three seasons, so the games have been a lot closer than the series. The Hoosiers haven’t beaten the Wolverines in 30 years, and only once in 50.

Michigan returned only one starter this season on defense. That hasn’t hurt the stat sheet. The Wolverines lead the nation with 7.7 three-and-outs per game, have forced 52 punts, allowed only 20.5 percent of third downs to be converted, and held all six opponents to their lowest yardage of the season.

In the five games since being shackled at home by Oklahoma 31-16, Ohio State has averaged 53.2 points and 619 yards a week.

Nebraska’s home sellout streak continues, closing in on 360 games in a row, but that hasn’t done much good on the scoreboard lately. The Cornhuskers have dropped three games at home, and just gave up 38 points to Wisconsin and 56 to Ohio State.

In seven games, Army has thrown 38 passes and completed eight of them for 125 yards. Doing their traveling on foot, the Black Knights are 5-2.

Hawaii has blocked five kicks this season. Utah State has blocked four punts.

Stanford’s Bryce Love is averaging 198 yards rushing a game. The next highest in the nation is Navy’s Zach Abey at 169.3.

Oklahoma’s Baker Mayfield is completing 72.7 percent of his passes and has a 17-1 touchdown-interception ratio.

Finally, five teams have yet to win. Two of them – 0-5 Georgia Southern and 0-6 UMass – play Saturday. Something has to give in Amherst.
