Aaron Rodgers tore up the Texans defense with 6 touchdown passes, and the Packers as the Texans dropped to 5-1 and 0-1 on Sunday Night Football. On the second drive of the game, Aaron Rodgers threw a touchdown to James Jones to make it 7-0. A few drives later it was 14-0 on a Rodgers to Jones touchdown.
