Offensively:  We are set bigtime, and for a long time.  We have a franchise QB in Kaep, we have our receivers in Crabtree and the returns of Manningham and Kyle Williams, we have Vernon and Delanie at TE, and last but not least we have outstanding depth at RB with Gore, James, Dixon, and the return of Kendall Hunter.  With another year under their belts, this offense will be top 3 in the league.

Defensively:  We have a lot of very good pieces.  I think the two biggest things that will help is getting Justin Smith and Aldon Smith healthy, so that they can return to their dynamic duo selfs.  We need better quality depth for the defensive line, which should come from a draft in which we have 10+ picks.  That way it will help keep everyone fresh.  Lastly I think we need to trade for a top CB.  Darrell Revis comes to mind.

Special Teams:  Obviously a new Kicker.  Aker's is done.  Better coverage teams.  That kickoff return to start the second half was a killer, and probably the difference in the game.  We need to find a home run hitter in the return game.

Think about it.  For eight seasons, the 49ers did nothing.  No playoffs, and not even a winning season.  Then Harbaugh comes in, and everything changes.  NFC title game appearance in 2011.  Then an NFC Title, and a narrow loss in the Superbowl.  Next year it's going to be a Superbowl Championship!  This team is young, and stacked.
