MIAMI GARDENS — The Miami Dolphins have been doubted for their ability to keep lengthy drives going without hitting the big play over the past two seasons. On Sunday against the Las Vegas Raiders, it was exactly how they did most of their damage. The Dolphins sustained three drives of around eight minutes before then making the big play late and won at Hard Rock Stadium for the first time in more than two months, 34-19, Sunday afternoon. Miami (4-6) wins a second consecutive game after last Monday night’s victory against the Los Angeles Rams on the Pacific coast.
