A statistical look at the 2011 college football season

Each week during the season, we looked at some statistics involving individuals and/or teams that we found intriguing. Here is our season-ending version, focusing on one team (Alabama, specifically the defense) and one individual (Houston QB Case Keenum).

Alabama's defense was as dominating as any in recent memory. The Tide led the nation in total defense (183.6 yards per game), rush defense (72.2 ypg), pass defense (111.5 ypg), pass efficiency defense (83.69 points) and scoring defense (8.2 points per game).

Alabama also led the nation in third down conversion percentage defense, allowing foes to convert just 24.5 percent of their opportunities. That's one reason the Tide defense played fewer downs (720) than any other defense in the nation. Army (726) was second, and only nine defenses nationally were on the field for fewer than 800 plays.

Those are staggering numbers across the board. The last defense to allow fewer than 200 yards per game was Alabama in 1992 (194.2 ypg), and this season's Tide surrendered the fewest yards per game since Oklahoma in 1986 (169.6 ypg). The points-per-game total is the lowest since 1988, when Auburn gave up just 7.2 per game.

But as talented as Alabama's defense is, the schedule played a role in the Tide's great numbers. Get this: Alabama played one FBS team that was in the top 80 in offense (Arkansas, at 29th). The second-best offense Alabama faced? Mississippi State's, which ranked 84th overall. Eight of the Tide's 12 games against FBS opponents (we didn't include a game against FCS member Georgia Southern) came against teams that had offenses ranked 95th or worse, including five that were 100th or worse.

The bottom line: Alabama's defense was a stifling one, and the talent level was extremely high. But it's hard to call it the best defense in college football history because of the large number of punchless offenses it went against.

As for Keenum, he graduates with all the important passing records in NCAA history. He owns career records for passing yards (19,217), TD passes (155), completions (1,546), 300-yard games (38) and 4,000-yard seasons (three); actually, he had three 5,000-yard seasons. He also holds the career record for total offense (20,114 yards) and touchdown responsibility (178, 155 passing and 23 rushing).

Keenum broke the total offense record by an incredible 3,204 yards. He broke the passing yardage record by 2,145 yards, the record for TD passes by 21 and the completions record by 143. He broke the TD responsibility record by 28.
