I'll add another one.....we've reduced the penalties, and that's at least 2, if not 3 weeks now.
I also like Wilson's progression.
I'd disagree with our tackling. I've seen a decent amount of missed tackles, just not in this game. Chicago is probably the best tackling team in the league this year, and San Fran is a very very close 2nd. I also think back to the great Ravens and Steelers defenses of the last few years, and I don't think we're quite there yet.
The other good news is that our defense is very young, and can get better in most aspects.
