Croak, basically the article focuses on how many yards it takes an offense to score a single point. Also, how many yards a defense forces an opponent to gain before they score a single point. "Scoreability counts ALL points, not just those generated by the offense. The scoreboard does not care how those points get there, only that they do. Well-coached teams score points as many ways as possible. Scoreabilty rewards teams for proficiency in all phases of the game; Bendability applies the same rules to defense."
I know the article is long so I'll post a few highlight quotes below.
On Offense
"No team has scored more efficiently than the 49ers. San Francisco has produced a meager 1,815 yards of offense. But it has still managed to hang 167 points on the scoreboard. That's an incredible 10.87 Yards Per Point Scored. In other words, the 49ers are good for about one point with each first down.
Not only is that performance No. 1 here in 2011, it's on pace to set the record for scoring efficiency held by the 2007 Patriots. That 16-0 New England team needed just 11.17 Yards Per Point Scored.
The 2011 Patriots, meanwhile, help put in perspective the incredible efficiency of Harbaugh's crew. Bill Belichick's team has generated 2,847 yards of offense this year -- 1,032 more yards than the 49ers in just six games. But the Patriots have scored just 18 points more.
....The importance of efficiency is far more dramatic if we put Scoreability in the context of touchdowns.
The 49ers need just 76.1 yards of offense to score the equivalent of 7 points. The St. Louis Rams are dead last in Scoreability: they need 225.9 yards of offense to score the equivalent of 7 points.
...Believe it or not, 5-1 San Francisco and 0-6 St. Louis are almost dead even in total offense: 1,815 yards for the 49ers; 1,807 for the Rams. But the 49ers have scored 167 points; the Rams have scored just 56."
On Defense
"The same benefit of efficiency applies to defense, where San Francisco is No. 1 in Bendability. They force opponents to march a spirit-killing 20.76 Yards Per Point Allowed.
In the context of touchdowns, San Francisco's opponents need 145.3 yards of offense to put 7 points on the board. They have the best "bend-but-don't-break" defense in football. Opponents may generate a lot of yards, but they do very little with all that effort."
Models of Inefficiency
"Norv Turner's Chargers are a prime example of a team that consistently possesses boatloads of talent but that fails to live up to expectations.
The 2010 Chargers, for example, were No. 1 in both total offense and total defense. Yet they went 9-7 and failed to make the playoffs. The problem? The consistently dumb, inefficient Chargers ranked No. 28 in Bendability, meaning they surrendered a lot of cheap points that made it hard to win games.
The 2011 Chargers are even worse: No. 31 in Bendability. Only the winless Colts surrender more cheap points.
The Philadelphia Eagles are the poster child of a talented but dumb football team here in 2011... The Eagles rank No. 28 in both Scoreability (18.28 Yards Per Point Scored) and Bendability (14.12 Yards Per Point Allowed).
They waste a lot of effort on offense, generating yards with little to show for it. Then they compound the problems on defense, by giving up a lot of cheap points that make it hard to win games."
