We don't need top performance from our QB on Sunday to get in the playoffs. What we need is a good team game with a QB who is safe with the ball and a balanced run attack with strong defensive effort. All those things are well within reasonable expectations too, for me at least.
I also think Wolford will look deep a bit more than Goff was. He's fresh and unmolested by defenses this year so I expect he will give us a boost. As long as he doesn't throw early game INTs I expect he'll get into rhythm and play very well.
