The 49ers will face the entire top-five quarterbacks of the 2011 season in passing yardage. New England’s Tom Brady, New Orleans’ Drew Brees, Green Bay’s Aaron Rodgers, Detroit’s Matthew Stafford and the Giants’ Eli Manning are all on San rancisco's schedule during the 2012 season. Secondary coach Ed Donatell compares the schedule to having a baby. “It’s like having a baby,” Donatell said. “You need about six to nine months to get ready to where you can say, ‘Yeah, we can take this on because the first day’s kind of tough … But by the time August rolls around, you say ‘OK, we have a plan for success and we can get this done.’”
