Answer based on context:

 After a disappointing loss to the Miami Dolphins, the Patriots looked to bounce back against the lowly Vikings who were without Adrian Peterson who was suspended, but were led by ex-Patriot Matt Cassel at quarterback. The Vikings took the ball and marched right down the field 80 yards in just 7 plays, with Cassel finding Matt Asiata on a 25-yard touchdown pass for a 7-0 lead just over four minutes into game. This would the highlight of the game for the Vikings. After a Patriots three-and-out, safety Devin McCourty intercepted Cassel at the Patriots 39 and returned it 60 yards down to the 1 yard line. Two plays later, Stevan Ridley scored on a 1-yard run to tie the game. After a Vikings punt, the Patriots reached the Vikings 30-yard line where Gostkowski gave the Patriots a 10-7 lead on a 48-yard field goal from Gostkowski. On the fifth play of the Vikings' next drive, Cassel threw his second interception, this one to Darrelle Revis at the Patriots 39. The Patriots put together a 7 play, 61-yard drive, with Brady finding Edelman for a 9-yard touchdown pass, increasing the Patriots lead to 17-7. Late in the second quarter the Vikings drove to the Patriots 30, but Chandler Jones blocked Blair Walsh's field goal attempt and returned it 58 yards for a touchdown, widening the Patriots lead to 24-7 at halftime. The Patriots reached the Vikings 43 early in the third quarter, but were forced to punt, but the Vikings gave it right back when Cassel threw his third interception, this one to Ryan at the Vikings 45. The Patriots could only reach the Vikings 28, where Gostkowski was connected on a 46-yard field goal and the Patriots led 27-7. Following another Vikings punt the Patriots stormed to the Vikings 9, but their struggling offense couldn't get in the endzone, and Gostkowski's 39-yard field goal gave the Patriots a 30-7 lead. With less than seven minutes remaining in the game, rookie Dominique Easley intercepted Cassel at the Vikings 35. Neither team did anything for the rest of the game and the Patriots won the game. Brady was efficient completing 14 of 21 passes for 149 yards, one touchdown, and no interceptions, but continued to not be the superstar that he was known to be. Stevan Ridley led the Patriots in rushing, carrying the ball 25 times for 101 yards and a touchdown. Filling in for the suspended Adrian Peterson, Matt Asiata carried the ball 13 times for only 36 yards. Matt Cassel went 19 of 36 for 202 yards with 1 touchdown, but was intercepted 4 times by the Patriots.
