The San Francisco 49ers have been very aggressive so far in the off-season.  They have re-signed nine of their own guys so far this off-season and they have also signed seven free agents.  Here’s a look at what they have done so far this off-season:

Offensively:  The 49ers flirted with signing Peyton Manning before he went to the Broncos.  After they lost out on him, they quickly re-signed Alex Smith.  The 49ers have added Mario Manningham and Randy Moss to the WRing corps and that should make Alex Smith happy.  The Niners also have signed RB Brandon Jacobs, who will team with Frank Gore to give them an outstanding RB tandem for 2012.  The Niners have also brought back WRs Ted Ginn and Brett Swain to help out on offense and special teams in 2012.  RB Rock Cartwright was brought in to help the Niners with depth at RB and on special teams where he excels.  QB Josh Johnson was brought in to compete for the #2 job behind Alex Smith in 2012.

Defensively:  The two big moves the Niners made were in bringing back safety Dashon Goldson (with the franchise tag) and LB Ahmad Brooks.  The 49ers have also brought back LB Tavares Gooden, CB Tramaine Brock, DE/DT Will Tukuafu and safety C.J. Spillman.  The Niners also bought low on CB Perrish Cox and he has a big upside if he can keep out of trouble.

Special Teams:  The Niners have signed long snapper Ryan Pontibrand.  They also brought back all-world return man Ted Ginn.

GRADE FOR THE OFF-SEASON SO FAR:  A

The 49ers have re-signed WR Brett Swain.  Swain played in 5 games for the Niners last year and he caught 2 passes for 15 yards (7.5 avg).  He has now played in 27 games in his first three years in the NFL and he has caught 8 passes for 87 yards (10.9 avg).  He also had has six tackles so far in his career.  This was a good move for the Niners as Swain will give them depth at WR, while also helping out on special teams.

The 49ers have signed 29-year old RB Brandon Jacobs to a 1-year deal.  Jacobs played in 14 games (6 starts) for the New York Giants last year and he carried the ball 152 times for 571 yards (3.8 ypc) with 7 TD runs.  He also caught 15 passes for 128 yards (8.5 avg) with 1 TD grab last year.  Jacobs has now played in 100 games (48 starts) in his first 7 years in the NFL and he has carried the ball 1,078 times for 4,849 yards (4.5 ypc) with 56 TD runs.  He has also caught 80 passes for 730 yards (9.1 avg) with 4 TD grabs so far in his NFL career.  This was an outstanding move for the Niners as Jacobs will team with Frank Gore to make the running game even better in 2012.

The Niners have re-signed 26-year old WR/PR/KR Ted Ginn Jr. to a 1-year deal.  Ginn played in 14 games for the Niners last year and he caught 19 passes for 220 yards (11.6 avg) and he also carried the ball 8 times for 68 yards (8.5 ypc).  Ginn also returned 38 punts for 466 yards (12.3 avg) with 1 TD return and 29 kickoff returns for 800 yards (27.6 avg) with 1 TD return.  Ginn has now played in 27 games in his first two years with the Niners and he has caught 31 passes for 383 yards (12.4 avg) with 1 TD grab and he has also carried the ball 10 times for 79 yards (7.9 ypc).  Ginn has also returned 62 punts for 787 yards (12.7 avg) with 2 TD returns and he has also returned 76 kickoffs for 1,792 yards (23.6 avg) with 1 TD return.  This was a good move for the Niners as Ginn will help out on offense and excel on special teams in 2012.

The 49ers have signed 25-year old QB Josh Johnson to a 2-year deal.  Johnson played in 9 games (1 start) for the Buccaneers last year and he completed 19 of 36 passes (52.8%) for 246 yards with 1 TD pass and 2 INTs (60.6 QB Rating).  He also carried the ball 11 times for 67 yards (6.1 ypc) last year for the Bucs.  Johnson has now played in 26 games (5 starts) in his first three years in the NFL and he has completed 96 of 177 passes (54.2%) for 1,042 yards with 5 TD passes and 10 INTs (57.7 QB Rating).  Johnson has also carried the ball 37 times for 254 yards (6.7 ypc) so far in his NFL career.  Johnson is 0-5 as a starting QB in his NFL career so far.  Johnson will compete with Colin Kaepernick for the #2 QB job on the Niners this year.  49ers’ head coach Jim Harbaugh was Johnson’s head coach at San Diego, when he coached there.

The San Francisco 49ers have re-signed 27-year old QB Alex Smith to a 3-year deal.  Smith played in 16 games (all starts) for the 49ers last year and he completed 273 of 445 passes (61.3%) for 3,144 yards with 17 TD passes and 5 INTs (90.7 QB Rating).  Smith also carried the ball 52 times for 179 yards (3.4 ypc) with 2 TD runs last year.  Smith has played in 70 games (66 starts) in his first six years with the Niners and he completed 1,137 of 1,959 (58%) passes  for 12,543 yards with 68 TD passes and 58 INTs (76.4 QB Rating).  Smith also has carried the ball 181 times for 629 yards (3.5 ypc) with 4 TD runs so far in his career.  Smith is now 32-34 (48.5%) as the Niners’ QB.  It was smart of the Niners to bring him back as he led them to a 13-3 record last year.

The 49ers have signed 25-year old WR Mario Manningham to a 2-year deal.  He played in 12 games for the Giants last year and he caught 39 passes for 523 yards (13.4 avg) with 4 TD grabs.  He has now played in 49 games in his first four years in the NFL and he has caught 160 passes for 2,315 yards (14.5 avg) with 18 TD grabs.  This was a great pickup for the Niners as their WRing corps is looking better by the day.  Manningham, Randy Moss and Michael Crabtree look like a pretty good set of wide receivers for whoever the QB will be in 2012.

The 49ers have released 30-year old CB Shawntae Spencer.  Spencer played in 9 games for the Niners last year and he had 5 tackles and 1 pass defensed.  Spencer played in 98 games in his eight years with the Niners and he had 345 tackles, 2.5 sacks, 6 tackles for a loss, 11 interceptions (one returned for a TD), 58 passes defensed, 3 forced fumbles and 3 fumble recoveries.  The Niners won’t miss Spencer too much, if at all, moving forward as he didn’t add much to the team last year.

The 49ers have signed 32-year old RB Rock Cartwright to a 1-year deal.  Cartwright played in 15 games for the Oakland Raiders last year and he carried the ball 4 times for 45 yards (11.3 ypc).  He also caught 4 passes for 24 yards (6.0 avg) last year.  Cartwright didn’t stop there as he also had 12 tackles and 3 kickoff returns for 15 yards.  Cartwright has now played in 154 games in his first 10 years in the NFL in which he has carried the ball 228 times for 956 yards (4.2 ypc) with 6 TD runs and he has caught 64 passes for 589 yards (9.2 avg) with 2 TD grabs.  Cartwright has also returned 231 kickoffs for 5,450 yards (23.6 avg) with 1 TD return and he has 96 tackles and 3 forced fumbles.  Anything Cartwright contributes offensively will be icing on the cake, as the Niners signed him for his special teams work.

The Niners have re-signed 27-year old LB Tavares Gooden to a 1-year deal.  Gooden played in all 16 games for the 49ers last year and he had 11 tackles and 2 forced fumbles.  Gooden has now played in 42 games in his first four years in the NFL and he has 81 tackles, 2 forced fumbles, 1 pass defensed and 3 tackles for a loss.  It was a smart move for the 49ers to bring back Gooden for 2012 as he will given them solid depth at LB while also helping out on special teams.
