San Fran is overrated and will struggle this season coming off the Super Bowl loss. They will miss Crabtree big time but the bigger issue will be relying on Kaepernick to stay healthy in the read option. The Pack have had plenty of time to prepare after getting their asses handed to them in the playoffs last year and they will be ready today. I expect a low-scoring affair here and the Pack will make a big play late to steal it.
