In celebration of the 49ers remarkable turnover this season, Niner Noise has reviewed each position and handed out grades.  Today also marks the one year anniversary of the hiring of Jim Harbaugh.  Who would have thought the 49ers would be in the playoffs as a second seed and winners of the NFC West a year ago from today?

The 49ers season of revival in 2011 was engineered by Harbaugh as he brought in the right coaches, kept the rights one from the previous regime, and installed the offense, defense and special teams.  No matter how good the coaches or the system a team sets up, you have to execute everything on the field when it counts.  The 49ers at all positions this season accomplished this.  A perfect storm of the right coaches, players peaking with career seasons that included players already on the roster, along with the free agents signed by the 49ers, came together to catapult them back into the playoffs.  Here is a look back at the 49ers 2011 season:
