The 2009Miami Dolphins season was the organization's 40th season in the National Football League and 44th overall. The Dolphins entered the 2009 season as the reigning AFC East champions after posting an 11–5 record in 2008. Dropping four more games in 2009, they failed to make the playoffs, marking the 25th consecutive year that the region hosting the Super Bowl would not see its host team play in it (not counting, of course, the years where Super Bowls have been played on neutral sites).
The Dolphins fired offensive line coach Mike Maser on January 14, 2009, just one year after he was hired to head coachTony Sparano's staff. During Maser's lone season with the Dolphins, the team had the 12th-best offensive in the league with 345.6 yards per game. A day after firing Maser, the team hired Dave DeGuglielmo, who had been the assistant offensive line coach for the New York Giants, as their new offensive line coach.
Originally slated to have the 26th overall pick in the 2009 NFL Draft, the Dolphins' pick moved up one spot to 25th after the Arizona Cardinals and Philadelphia Eagles made it to the NFC Championship. Both the Cardinals (9–7) and Eagles (9–6–1) were projected to pick before the Dolphins (11–5), but with one guaranteed to make the Super Bowl (and thus pick 31st or 32nd depending on the outcome) the Dolphins moved up one position in the draft.
The team later signed guard J. D. Quinn (Montana) on May 11. Two of the undrafted rookies would end up leaving the team shortly after signing, with Bronson failing to report to training camp on August 2 and Rogers opting for retirement on August 6.
After a great season for the Miami Dolphins in 2008, the Dolphins went to the Georgia Dome to take on 2008 playoff contenders, the Atlanta Falcons.
After a scoreless first quarter, the Falcons got on the board with a 1-yard touchdown pass from Matt Ryan to fullback Ovie Mughelli in the second quarter. They also got a 36-yard field goal by kicker Jason Elam to make the score 10–0 at halftime. In the third quarter, Mike Peterson intercepted a Chad Pennington pass, which set up a 20-yard touchdown pass to tight end Tony Gonzalez and a 50-yard field goal by Jason Elam to make the score 19–0. Chad Pennington then hit a 9-yard touchdown pass to Ricky Williams.
The Falcons won the game 19–7.
In 2008, no other team turned the ball over less than the Dolphins with only 13 turnovers, but in Week 1 Miami's offense had 4 turnovers, without having a single turnover on defense.
After a miserable loss to the Atlanta Falcons, the Dolphins host their home opener to the Indianapolis Colts. On the first play from scrimmage, Peyton Manning threw an 80-yard touchdown pass to tight end Dallas Clark. The Dolphins answered with a 14-yard touchdown run by Ronnie Brown out of the Wildcat Offense. The Dolphins and Colts kept going back and forth at each other with two field goals by Dan Carpenter and Adam Vinatieri to make the score 13–13 at halftime. After a scoreless third quarter, Ronnie Brown ran 2-yards for a touchdown to put Miami up 20–13. The Colts answered back with a 15-yard touchdown run by rookie running back Donald Brown. Miami than hit a 45-yard field goal by Dan Carpenter. But the Colts took the lead thanks to a 48-yard touchdown pass to Pierre Garcon. The Dolphins tried to rally at the end of the game but Chad Pennington was intercepted by Antoine Bethea to sucure the Colts victory.
The Colts won the game 27–23.
The Dolphins dominated the game in the time of possession battle, but lost the game with almost 50 minutes of offensive possession.
After a scoreless first quarter, Nate Kaeding hit a 25-yard field goal to score the first points of the game. Miami would answer with a 24-yard field goal to tie the game at halftime 3–3. Miami would then take the lead after a 23-yard field goal by Dan Carpenter. But the Chargers would retake the lead with a 5-yard touchdoun run by Philip Rivers. The Chargers would pull away in the fourth quarter with two Nate Kaeding field goals and a 31-yard interception return by safety Eric Weddle. The Dolphins would get a 14-yard touchdown run by Ricky Williams, but couldn't make a comeback.
The Chargers won the game 23–13
Dolphins quarterback Chad Pennington left the game with a shoulder injury after being hit by linebacker Kevin Burnett and was out for the season. The Dolphins chose Chad Henne to lead the Dolphins for the rest of the season.
The final outcome of this game had somewhat of a domino effect. It resulted in the Dolphins' elimination from the post-season (including Super Bowl XLIV, which they hosted February 8, 2010), and also, by virtue of the final standings' tiebreaker (as the result of the Baltimore Ravens defeating the Oakland Raiders), the Steelers themselves being dethroned of their world title defense.
