Come on man, this is just ignorance... Do you know anything about the 49ers? They added Michael Lewis and Nate Clements to their defense, had one of the best drafts of any team in the League, and added Darrell Jackson and Ashley Lelie on offense and Vernon Davis missed six games. Besides, what's to stop some of the other teams on their schedule from regressing? And also, their schedule, based on how these teams did last year, should be in the upper half of the League for easy schedules, not the lower half.
They're considered to have one of the top off-seasons along with New England and Denver... how can a young team that took huge strides last year and added so much veteran talent look primed to regress?
