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."
