Actually, I believe it came into the game 2nd or 3rd worst, didn't it?
I don't care though, man. So much of running the ball comes down to confidence. They also (from what I saw - didn't watch it all) rotated Snyder in a lot more. Frank Gore isn't done, man. San Francisco's O-line has been playing like the worst O-Line in football (11 sacks through the first 3 games after 0 in the first, and an unimaginable number of pressures). Whatever way you slice it, these games aren't pretty, but San Fran is an overtime away from being 4-0 and just won two on the road. For a team that hasn't been to the playoffs in what, 9 years, that's fucking HUGE! This is a TEAM and they are buying in to Harbaugh.
Alex Smith also threw for over 200 yards with a couple td's sprinkled in there in the second half. Stretching the field, spreading things out, this is what they have to do to run the ball effectively with a substandard line. Vernon was great - had some nice blocks too, Morgan had over 60, Crab is healthy and had over 60, Edwards isn't even playing yet. This team is going to keep improving. They've only been in this system for about, what, a little over 2 months?
It should be said that SF also has one of the very best front sevens in the league on D. They're playing great football - especially guys like Bowman, Sapoaga, and Ray McDonald, who have really stepped in to their roles nicely!
