Offense: Whether it was due to steady rain, a soggy surface or his rapidly dwindling offensive line, C.J. Beathard was off target on short throws, medium throws and long throws on Sunday. The rookie quarterback did show moxie, though, in rushing for 40 yards, and his jersey was dingy gray by game's end. Grade: D-
Defense: By the fourth quarter, the 49ers defensive line consisted of DeForest Buckner, Earl Mitchell, Leger Douzable, Tony McDaniel and Datone Jones. Considering all the newcomers, it's an achievement the 49ers allowed 306 yards. The group gave up 501 yards a week ago.
