49ers at Eagles, 1 p.m., Line: Eagles by 13

The 49ers (0-7) are very bad. The Eagles (6-1) are very good. The Birds will take care of business at home against a winless opponent, but a spread of 13 points is demanding a blowout, and San Francisco’s plucky young defense may be up to the task of preventing that from happening. As good as the Eagles have been, they have kept things close in four of their six wins, and they have little reason to try to run up the score against an overmatched opponent.
