The Dolphins have signed 33-year old QB Sage Rosenfels.  Rosenfels played in 12 games (0 starts) for the New York Giants last year but he didn’t throw any passes.  He did carry the ball 3 times for -3 yards (-1.0 ypc) last year.  Rosenfels has now played in 44 games (12 starts) in his first 9 years in the NFL and he has completed 351 of 562 passes (62.5%) for 4,156 yards with 30 TD passes and 29 INTs (81.2 QB Rating).  He has also carried the ball 48 times for 95 yards (2.0 ypc) with 1 TD run so far in his NFL career.  Rosenfels is 6-6 as a starting QB in the NFL so far in his career.  Rosenfels might push Matt Moore for the starting job at QB in the near future.

UPDATE:  (10/26/2011) – The Dolphins have placed Sage Rosenfels on the Injured Reserve list, ending his season, due to an undisclosed illness).

UPDATE:  (12/1/2011) – The Dolphins have waived Sage Rosenfels.

The Dolphins have signed 29-year old DE Igor Olshansky.  Olshansky played in all 16 games for the Cowboys last year and he had 38 tackles, 1 tackle for a loss and 2 passes defensed.  He has now played in 107 games in his first 7 years in the NFL and he has 257 tackles, 12.5 sacks, 12 tackles for a loss, 3 forced fumbles, 1 fumble recovery, 8 passes defensed and 1 interception.  This was a good signing for the Dolphins as you can never have too many quality DEs on your roster.

The Dolphins have signed 29-year old cornerback Nate Jones.  Jones played in all 16 games for the Broncos last year and he had 57 tackles and 3 passes defensed.  He played with the Dolphins in 2008+2009.  He played in 32 games in his two years with the Fins and he had 77 tackles, 11 passes defensed, 3 interceptions, 4 sacks, 2 forced fumbles and 1 fumble recovery.  Jones has now played in 99 games in his first 7 years in the NFL and he has 212 tackles, 16 passes defensed, 3 interceptions, 3 forced fumbles, 1 fumble recovery, 6 sacks and 1 tackle for a loss.  The Dolphins need all of the help in the secondary that they can get, so Jones is going to be a nice addition to the team.  To make room on the roster for Jones, the Dolphins have cut TE Dante Rosario.  Rosario played in both of the Fins games this year but he didn’t catch any passes.

The Dolphins have signed 28-year old offensive lineman Ryan Cook.  Cook played in 16 games (7 starts) for the Vikings last year.  He has now played in 70 games (40 starts) in his first five yeras in the NFL.  The Dolphins will benefit from Cook’s versatility along the offensive line as he can handle playing center, guard or tackle.

The Dolphins have signed 26-year old TE Dante Rosario.  Rosario played in 16 games (6 starts) with the Panthers last year and he had 32 grabs for 264 yards (8.3 avg).  He has now played in 62 games (22 starts) in his first four years in the NFL and he has caught 82 passes for 894 yards (10.9 avg) with 5 TD grabs.  Rosario is a decent TE who should be able to help the offense when he’s on the field.

The Dolphins have signed 27-year old safety Gerald Alexander.  Alexander played in 3 games for the Jaguars last year and he had 16 tackles, 1 fumble recovery and 3 passes defensed.  He has now played in 39 games in his first four years in the NFL and he has 159 tackles, 14 passes defensed, 4 interceptions, 2 sacks, 3 forced fumbles, 4 fumble recoveries and 1 tackle for a loss.  This was a good signing for the Dolphins so late in the preseason.

UPDATE:  (9/3/2011) – The Dolphins have released Gerald Alexander.

The Dolphins have signed 31-year old RB Larry Johnson.  Johnson played in 2 games (0 starts) for the Redskins last year and he carried the ball 5 times for 2 yards (0.4 ypc).  He has now played in 84 games (55 starts) in his first 8 years in the NFL and he has carried the ball 1,426 times for 6,221 yards (4.4 ypc) with 55 TD runs.  Johnson has also caught 154 passes for 1,373 yards (8.9 avg) with 6 TD grabs in his NFL career.  Johnson will have a good shot to beat out Lex Hilliard for the #3 RB in 2011, if he can show that he still has a lot left in the gas tank the next couple of weeks.  I like this move for the Dolphins as they don’t have much to lose in giving Johnson a tryout.

UPDATE:  (9/4/2011) – The Dolphins have released Larry Johnson.

UPDATE:  (9/8/2011) – The Dolphins have re-signed Larry Johnson.

The Dolphins have signed 26-year old linebacker Marvin Mitchell.  Mitchell played in all 16 games for the Saints last year and he had 43 tackles, 1 sack, 2 tackles for a loss, 2 forced fumbles, 2 fumble recoveries and 2 passes defensed.  He has now played in 55 games in his first four years in the NFL and he has 89 tackles, 1 sack, 3 tackles for a loss, 2 forced fumbles, 2 fumble recoveries and 2 passes defensed.  This was a good signing for the Dolphins as Mitchell will give them depth at LB while also helping out on special teams.

The Dolphins have signed 26-year old linebacker David Nixon.  Nixon played in 4 games for the Rams and Texans last year and he had 10 tackles.  Nixon has now played in 7 games in his first two years in the NFL and he has 10 tackles.  This was a depth signing for the Dolphins and little more.  If Nixon is going to make the Dolphins’ roster, he’s going to have to do it on special teams.

The Dolphins have signed 28-year old OT Ray Willis.  Willis didn’t play last year for the Seahawks due to injury.  He has played in 44 games (26 starts) in his first six years in the NFL.  This was a good signing for the Dolphins as you can never have too many quality offensive linemen on the roster.
