The Patriots traveled to Miami to face their division rival Miami Dolphins in the 2014 season opener. The Patriots featured several key additions: Brandon LaFell, Darrelle Revis, and Brandon Browner (even though he was suspended for the first four games). After forcing a Patriots three-and-out, Chris McCain blocked the punt by Ryan Allen with Jason Trusnik recovering at the Patriots 15. Four plays later, Lamar Miller scored on a 4-yard touchdown pass from Ryan Tannehill, for a 7-0 Dolphins lead. The Patriots responded, marching 80 yards in 13 plays, with Shane Vereen tying the game on a 2-yard run. On the third play of the Dolphins next drive, Mike Wallace was stripped by Jamie Collins with Jerod Mayo recovering at the Dolphins 35. The Dolphins  defense stiffened, and held New England to a 47-yard field goal by Stephen Gostkowski. The Dolphins responded by driving all the way to the Patriots 37, but Alfonzo Dennard intercepted Tannehill at the Patriots 6-yard line. The Patriots proceeded to march 94 yards in 11 plays, aided by a 44-yard bomb from Tom Brady to Julian Edelman, culminating with Brady finding Rob Gronkowski on a six-yard touchdown pass giving the Patriots a commanding 17-7 lead midway through the second quarter. After reaching their own 47, the Dolphins turnover woes continued with Logan Ryan stripping Miller and Darrelle Revis recovering at the Patriots 34. The Dolphins defense stiffened and the Patriots punted. The Dolphins answered with a drive deep into Patriot territory, but had to settle for a 38-yard field goal from Caleb Sturgis, trimming the score to 17-10 with 1:59 to go in the half. A 30-yard kickoff return by Patrick Chung and a 33-yard catch by Edelman, helped the Patriots reach the Dolphins 27 where Gostkowski drilled a 45-yard field goal, giving the Patriots a 20-10 at halftime. The second half was a different story entirely. The Dolphins stormed all the way to the Patriots 6-yard line on their first possession, but the Patriots defense clamped down and held the Dolphins to a 24-yard field goal to trim the lead back to 7. On the fourth play of the Patriots next drive, Brady was strip-sacked by Cameron Wake with Louis Delmas recovering at the Patriots 34. Four plays later Tannehill found Wallace for a 14-yard touchdown pass to tie the game midway through the third quarter. Following a Patriots three-and-out, the Dolphins were set up with good position at their own 47. They reached the Patriots 3, but once again the Patriots clamped down and Sturgis booted a 21-yard field goal, regaining the lead for the Dolphins, 23-20. It only got worse for New England. Early in the fourth quarter, facing a 3rd-and-9 at the Dolphins 44, Brady had his best pocket of the 2nd half, but overthrew an open Edelman and the Patriots punted. The Dolphins pulled away on their next drive, methodically marching 85 yards in 12 plays, converting three third-downs, with Moreno rushing for a 4-yard touchdown, increasing the Dolphins lead to 30-20 with just 3:29 remaining in the 4th quarter. Any hope of a Patriots comeback died on their next possession when Brady was sacked by Anthony Johnson on 4th-and-10. The Dolphins didn't get a first down, but Sturgis' 27-yard field goal, his 4th, was good and the Dolphins led 33-20. The Patriots drove deep into Miami territory in the final seconds, but turned the ball over on downs. The loss was the Patriots first to open a season since losing 31-0 to the Buffalo Bills in 2003. Tom Brady was sacked four times, losing two fumbles and finishing the day completing only 29 of 56 pass attempts, including 14/35 in the second half, for 249 yards and 1 touchdown. Edelman had 95 yards on just 6 catches, but Brandon LaFell, the new deep-threat, didn't have a single catch. The Patriots defense played well in the first half, forcing three turnovers and holding the Dolphins to just ten points, but allowed 23 points and forced no turnovers in the second half. Ryan Tannehill was efficient, 18 of 32 for 178 yards, 2 touchdowns, and 1 interception. Moreno ran for 134 yards, including 91 yards in the 2nd half, and the Dolphins as a team rushed for 191 yards and out-gained the Patriots in total yards in the second half, 222-67.
