49ers defense shines through all the distractions and doubts, forces 4 turnovers

So much for all that talk of distractions, letdowns and doubts about San Francisco's longtime dominant defense. One impressive first-half sequence handled all of that.

The 49ers made interceptions on three straight possessions in a 28-17 Week 1 win at Dallas on Sunday, and forced four turnovers in all. All that after both starting cornerbacks — Tramaine Brock and Chris Culliver — were injured. Perrish Cox again proved a reliable replacement.

The offense thrived, too, even with two fill-ins on the offensive line in Joe Looney and Jonathan Martin. The Niners' 21 first-quarter points — on all of four plays — were their most since 1995, and tight end Vernon Davis caught a pair of touchdown passes from Colin Kaepernick.

The 49ers have won their opener in all four seasons under coach Jim Harbaugh.
