Unfortunately for the Niners, who have an offense that was even more anemic, the game turned into a slog, a football version of trench warfare. San Francisco is better than it was last season, but mistakes -- 13 accepted penalties against them for 113 yards -- hurt in many moments, including on the final drive in overtime. Three of the Niners' four losses this season have come by three points or less. It's a heartbreaking way to lose, and when it keeps happening, can wear a team down, but this Niners team is making strides, and the penalties shows they're just a handful of corrections away from bringing home a win.
