After a tough loss to the Raiders, the Steelers traveled to Foxborough to take on the Patriots.  The Patriots scored first when Danny Amendola caught a 34-yard TD pass from Tom Brady to make the score 7-0.  In the 2nd quarter, the Patriots increased their lead as Brady found Rob Gronkowski on a 19-yard pass to make the score 14-0.  The Steelers finally got on the board when Shaun Suisham kicked a 30-yard field goal to make it 14-3, but the Pats went ahead by 2 touchdowns again as Stephen Gostkowski nailed a field goal from 20 yards out making the score 17-3.  Ben Roethlisberger regardless was able to find Antonio Brown for his 200th career TD pass a 27-yarder to come behind by 7, 17-10.  But the Pats pulled away as Steven Ridley ran for a 1-yard TD to make it 24-10 at halftime.  In the 3rd quarter, Roethlisberger found Cotchery again on a 20-yard pass cutting the lead to 24-17 and again on an 8-yard pass tying the game at 24.  However, the Patriots pulled away again as Gostkowski kicked a 32-yard field goal to make the score 27-24.  They continued to dominate in the 4th quarter scoring a total of 17 straight points as Brady found Aaron Dobson on a 17-yard pass to make the score 34-24 and Ridley again ran for another TD from 5-yards out making the score 41-24.  Roethlisberger and Cotchery hooked up again on a 6-yard pass to shorten the lead to 41-31, however the Patriots were able to pull away as Brady found Dobson again on an 81-yard pass to make the score 48-31 and ended it with LeGarrette Blount's 5-yard run making the final score 55-31. With the loss, the Steelers dropped to 2-6.  The team's first such start since 2006.  It may also be noted that since 2006 whenever the team has been below .500 in a season, they would eventually finish with 8 wins or more, but at the same time, miss out on the playoffs.  Also, the 55 points are the most points ever scored against the Steelers as the Patriots became the first team to score 50+ points against the team since the Bills' victory of 52-34 in 1991.
