I can't go solely by last year and what happened about the points. It is a different year.
Dallas run defense looks better this year so far, except against that Cardinals game. Was it an outlier, or a trend (again) with break downs. SF has very good skill players in a RB, 2 WR's and a TE.
Purdy drives Shannehans bus pretty good as the OL gives him protection.
But have they faced a pass rush like ours yet? A lot more game film on him now, can DQ dissect that.
I have no thoughts about our offense against their defense. Other than I think we can move the ball on them, but can we get TD's, as FG's sure will not win us the game. Unless our defense comes up big again and gets us a few scores.
Do I think we can win, yes, but it will not be very easy. Things need to go almost perfect, and get some lucky bounces, they may need to make more mistakes than we do.
