The Cowboys (5-4) have won consecutive games and could be at the start of a big surge. Their next three opponents went into this weekend a combined 6-18.
Romo completed his first 13 passes, including touchdown strikes of 34 yards to Dez Bryant and of 58 and 5 yards to Laurent Robinson. Romo finished 23 of 26, setting the franchise record for single-game accuracy by hitting on 88.5 percent of his passes.
The 37-point margin of victory was the biggest for Dallas since Oct. 22, 2000. The Cowboys hadn't scored this many points since Sept. 9, 2007.
Buffalo (5-4) lost its second in a row.
