How could anyone familiar with the defending NFC West champions project only seven victories for the coach Jim Harbaugh's second season? After all, the 49ers are bringing back all of their most important players -- Harbaugh's mighty men, as the coach likes to call them -- from a squad that went 13-3 and nearly reached the Super Bowl.
Here is the deal: Even Schatz himself, lead author of the 2012 Football Outsiders Almanac, believes the 49ers will outperform the modest expectations set forth by his book's widely cited win projection system.
"Subjectively, I'd expect the 49ers to win the division at 9-7," Schatz said Tuesday during an hour-long conversation on all things NFC West.
Anyone interested in more fully understanding the projection system can find an explanation, plus detailed reports for every NFL team, in the almanac Football Outsiders made available for sale recently.
I've singled out key points for consideration here and will run through one per NFC West team, supplemented as needed with material from my conversation with Schatz.
Yes, the Cardinals posted a 5-2 record when Skelton started and a 3-6 mark when Kolb was in the lineup. Skelton was even the primary quarterback during one of those victories credited to Kolb. (He performed rather impressively during an upset over the 49ers after a concussion sidelined Kolb early in the game.)
The disparity in win-loss records largely accounts for coach Ken Whisenhunt's decision to let Skelton compete with Kolb for the starting job in camp. But the way Schatz sees things, that thinking ignores the context for each player's performance.
"Skelton got away with close wins playing an easier schedule, and the idea that he had more wins and therefore is a better quarterback, no way," Schatz said. "Should there be a battle between Kolb and Skelton? No, it's silly."
For evidence, the almanac points to the schedule. The New York Giants, Pittsburgh Steelers and Baltimore Ravens were on the schedule right before an injury to Kolb opened the door for Skelton. The Cardinals then played St. Louis twice and the then-struggling Philadelphia Eagles with Skelton in the lineup. And they needed some miraculous plays, including punt returns for touchdowns from Patrick Peterson, to eke out victories over the Rams.
The assessment shoots down Skelton more than it endorses Kolb, but there are obvious reasons for the organization to take a longer look at Kolb this season.
Kolb had very little prep time following his acquisition last summer. Injuries kept him off the field for long stretches. The team also invested millions in Kolb. The point is basically that Skelton, despite his 5-2 starting record, hasn't shown enough for the team to disregard all those factors.
"Frankly," the almanac concludes, "even if Kolb or Skelton does a reasonable job, the Cardinals will still be in the market for a franchise quarterback in the 2013 draft."
The point: History suggests new quarterback Matt Flynn will be at least serviceable, and probably better than that, despite extremely limited evidence (two career starts, 132 career attempts).
Schatz, writing recently for Insider , allowed that sample size generally means a great deal. But in looking at Flynn's 480-yard game for Green Bay against Detroit, a performance complete with six touchdown passes, Schatz made a basic conclusion.
"Bad quarterbacks simply don't have games that good, even as flukes," he wrote.
"Going back to 1991," Schatz wrote, "the worst quarterback who had a single game this good was Scott Mitchell. As bad as Mitchell was at times, he also threw for more than 4,000 yards with 32 touchdowns and 12 interceptions in 1995. Seattle would gladly take those stats from Flynn."
The almanac actually projects slightly more victories for Seattle than for San Francisco (the mean projection is 7.2 for each, but the Seahawks' total is slightly higher). But much will hinge upon something that is uncertain: how good Flynn might become. Talk of rookie Russell Wilson possibly winning the starting job in camp didn't resonate with Football Outsiders, even if the Lewin Career Forecast suggests "Wilson can win in the NFL if he has an offensive coordinator who knows how to take advantage of his skills."
San Francisco 49ers
The point: There's almost no way the team will approach its 13-3 record from last season.
In covering this ground previously, I noted that the 13 teams finishing with 13-3 records from 2004 through 2010 had won 8.3 games on average the following season. Three finished better than 9-7. Over the same period, the 19 teams finishing 13-3 or better all finished with lesser records the next year. The average drop was 4.1 victories per team.
Schatz's reasoning for projecting a drop takes into account historical data.
"Teams that improve dramatically from one season to the next do tend to settle to previous levels in the third year," he said. "That is exacerbated for the 49ers by having the quality of their team wrapped up in defense and special teams. Offense tends to be most consistent from year to year. Special teams is the least consistent of the units. Defense is second. The 49ers' defense and special teams are likely to come back to the pack."
Schatz also thinks the 49ers were unusually healthy on defense last season, and that they'll most likely be less healthy in 2012. The 49ers current and former leadership put together their roster, particularly the defense, with size in mind. Former general manager Scot McCloughan, borrowing from Ron Wolf, believed bigger players held up better over the course of a season. The thinking intrigued Schatz, whose company tracks injury information. By combining injury information with data for size, might we have an easier time predicting injuries for certain players and teams?
"It's an interesting theory," Schatz said. "There are teams that no doubt have a record of better health. The 49ers do not quite count as one of those teams. They have been healthy on defense three of the last four years. Dallas is a team that tends to suffer fewer injuries. Kansas City was a team. Cleveland tends to suffer more. New England has suffered more than average and gotten away with it."
The point: Quarterback Sam Bradford wasn't all that much worse last season than he was as a rookie.
Bradford's individual passing stats were worse, but Rams fans worried about their team's franchise quarterback should find some consolation in Football Outsiders' analysis.
Basically, the Rams suffered injuries on a level nearly unprecedented over the past decade, all while facing a schedule that was tougher than anticipated.
Football Outsiders uses a metric called "Adjusted Games Lost" to measure injury impact. The 2011 Rams suffered a league-worst 110 AGL, which the almanac equates to "losing seven key players for the year in training camp." Only the 2009 Buffalo Bills (122.8 AGL) fared worse since 2002.
Meanwhile, the Rams became the first team since at least 1991 to go from playing the NFL's easiest schedule one season (2010, when the Rams were 7-9) to playing the hardest.
"On average," the almanac reads, "the 10 teams since 1991 with the biggest year-to-year rise in strength of schedule had 4.1 fewer wins."
The Rams declined by five victories from 7-9 to 2-14.
None of this means Bradford will lead the Rams to prominence. The evidence does suggest, though, that the Rams faced unusually difficult obstacles last season.
"Everything points to them being in process," Schatz said.
The upcoming season should be one of discovery, in other words. Absent some of those unusually difficult obstacles, the Rams will have an easier time evaluating their personnel. They'll find out more about Bradford, tackle Jason Smith, tight end Lance Kendricks and other potentially key players. They'll learn about their wide receivers and outside linebackers.
"In the end, though, the team's ultimate fate will lie in the hands of [coach Jeff] Fisher's first acquisition in St. Louis, offensive coordinator Brian Schottenheimer," the almanac predicts.
