It's been a busy couple days in the household, so there hasn't been much time to pick through Thursday's game.Thankfully, the good folks at Pro Football Focus do a thorough job of breaking down every player from every game with a one-of-a-kind grading system.Here are some of PFF's items that stand out from the 49ers' 13-6 victory over the Seattle Seahawks on Thursday night:--The 49ers' offensive line was outstanding. All five starting linemen graded out very well, according to the PFF, which takes into account pass-blocking, screen blocking, run-blocking and penalties.Each of the 49ers' five offensive linemen had strong games. Center Jonathan Goodwin graded out the best of the bunch, followed closely by a tie between guards Mike Iupati and Alex Boone. Left tackle Joe Staley was a shade behind, with Anthony Davis still maintaining a positive grade."A lot of times you talk about teams that can run well between the tackles," 49ers coach Jim Harbaugh said. "I've never seen a team run better between the guards than our team showed in the running game. And that was to great credit to Jonathan Goodwin and the two guards. Mike Iupati and Alex Boone had great games."The offensive line was not responsible for any sacks or quarterback hits. Staley gave up two hurries, and Davis surrendered one.--It was the best game of the season for running back Frank Gore, who gained 131 yards on 16 carries and also caught a team-high five passes for 51 yards.To prove the point that Harbaugh made in the previous item, Gore had six runs between the guards that gained 95 yards (15.8 average).--Third cornerback Chris Culliver, coming off a rough game against the New York Giants, picked up where he left off through five games. He was in coverage for 21 plays and his receiver was targeted six times. Culliver surrendered only two catches for 13 yards with two passes broken up. Golden Tate and Evan Moore had dropped passes with Culliver in coverage.--With Mario Manningham out with a shoulder injury (he said he'll be ready for the Monday, Oct. 29, game at Arizona), the 49ers ran sets with three wide receivers only 13.3 percent of the time. As a result, the 49ers kept the Seahawks' nickel defense off the field. Rookie pass-rush specialist Bruce Irvin was on the field for only 12 snaps.--Seattle defensive tackle Brandon Mebane entered the game as the second-highest rated player at his position in the league. And he graded out as the best defensive tackle in the NFL against the run.But against the 49ers, Mebane had an awful -5.7 grade, and credited with only one tackle and no stops. He had made stops on 12.9 of run plays prior to Thursday night. It was is first negative-grade game of the season and it was a big one. Oh, yeah, his defensive mates weren't much more successful against the 49ers.
