The Houston Texans have already won more games than they did in last year's dreadful 2-14 season.

While they're happy with their 3-1 start, they're still looking to do much more, especially with a matchup with in-state rival Dallas coming up on Sunday.

Defensive end J.J. Watt was named AFC defensive player of the week on Wednesday. Watt led the way in Houston's 23-17 win over Buffalo on Sunday with an 80-yard interception return for a touchdown, five tackles and a career-high nine hits on quarterback E.J. Manuel.
