Problem: The Dolphins entered their second game of the season with a 0-1 record, hosting the 0-1 Oakland Raiders. The game marked the third consecutive season game between the two teams and 36th all-time, with the Dolphins winning the last two games with an average margin of victory of 18 points. Miami opened the game with an impressive 80-yard drive after the opening kickoff, which lead to a quarterback Ryan Tannehill two-yard rushing touchdown. Two possessions later at the (3:28) mark in the first quarter, Oakland quarterback Carson Palmer threw a 64-yard touchdown to Mike Goodson tying the game. Through a majority of the second quarter both teams had a hard time moving across the 50-yard line, which was matched with impressive punting by both Dolphins punter Brandon Fields and Oakland punter Shane Lechler. By the end of the game Field punted the ball six times for 319 yards with an average yard per punt of 53.2 and Lechler punted the ball nine times for 422 yards with an average yard per punt of 46.9. However, Oakland managed to get the ball back with (3:33) left in the quarter and orchestrated a drive that ended with a Sebastian Janikowski 25-yard field goal. Both teams entered halftime evenly matched. It didn't take long following halftime for the Dolphins rushing attack to shine. On the second possession of the half the Dolphins drove the ball down field and allowed Reggie Bush to rush for a 25-yard touchdown. On the next Miami possession, after a quick pass from Tannehill to receiver Brian Hartline, Reggie Bush rushed 65 yards for another Miami touchdown. A few possessions later Oakland answered with a Janikowski 27-yard field goal. With little opposition from the Oakland defense Miami's offense kept the ball moving and managed to score on their next two possessions. Once with an Anthony Fasano 14-yard reception touchdown from Tannehill, the first of his career, and again with a Lamar Miller 15-yard rushing touchdown, the first of his career. Oakland tried to stop the bleeding on their next drive, but quarterback Palmer was intercepted by safety Reshad Jones. The impressive game of 172 rushing yards on 26 attempts by running back Reggie Bush earned him the week 2 AFC Offensive Player of the Week and FedEx Air and Ground rusher of the week honors.
