ARLINGTON, Texas -- Colin Kaepernick and the San Francisco 49ers can put a tumultuous off-season behind them. They have a rusty Tony Romo to thank for making the opener a little easier. Kaepernick threw two touchdown passes to Vernon Davis, one after the first of three interceptions from Romo, and the 49ers cruised to a 28-17 win over the sloppy Cowboys on Sunday. The 49ers (1-0) came in with questions about their defence, missing key players because of injuries or suspensions. Defensive tackle Ray McDonald got the start just a week after his arrest in a domestic violence case. The secondary put all those issues to rest, getting Chris Cullivers 35-yard fumble return for a touchdown on the second play of the game and two of the Romo picks on their way to a 28-3 halftime lead. "Theres been a lot of rhetoric," said coach Jim Harbaugh, who improved to 4-0 in season openers. "This game was about steel in the spine. When it comes to 49er players, thats where they excel." For one game, it didnt matter that linebacker Aldon Smith will miss the first nine games on a suspension over off-the-field issues and fellow linebacker NaVorro Bowman is out until midseason because of a knee injury. After Culliver picked up a loose ball stripped from DeMarco Murray and ran untouched for a score, safety Eric Reid returned Romos first interception 48 yards to the Dallas 2, setting up Kaepernicks second scoring toss to Davis. "Our front seven did a good job getting pressure on the quarterback, and the secondary played well," Reid said. Romo looked like a quarterback who was limited in the off-season and training camp, not a good start for a team trying to avoid tying a franchise record with a fifth straight year of missing the playoffs. He didnt see Reid on a throw to Dez Bryant, then didnt see wide-open receiver Dwayne Harris for what would have been an easy touchdown. Instead he forced a pass to Jason Witten that was intercepted by Patrick Willis in the end zone. The picks kept coming even after starting San Francisco cornerbacks Tramaine Brock (toe) and Culliver (concussion) had been knocked out of the game. Backup Perrish Cox had his second career interception when Romo threw deep to Bryant in double coverage. "I felt comfortable," said Romo, who threw for 281 yards and a late touchdown. "Just couple poor decisions that I made tonight." It didnt take Kaepernick long to put that rough preseason behind him, leading the 49ers 80 yards in just three plays on their first possession. He stepped out of an ankle tackle by Jeremy Mincey and threw 29 yards on the run to Davis, who juggled the ball as the crossed the goal line before holding on for a 14-3 lead. The 49ers also had an efficient drive in their 2-minute offence to finish the first half, with Kaepernick throwing for 39 yards leading to Carlos Hydes 4-yard scoring run for a 28-3 halftime lead. "Everyone was ready to get to the season, ready to play and ready to start putting these wins together," said Kaepernick, who was 16 of 23 for 201 yards without an interception. When Romo wasnt throwing interceptions, the Dallas offence was getting false-start penalties and using timeouts to avoid delay-of-game penalties. Part of the problem was the noise from large swaths of red-clad 49ers fans seeing their team for the first time in the regular season in the $1.2 billion home of the Cowboys. "I noticed that," Harbaugh said of the crowd. "Much appreciated. Means a lot." Murray bounced back from the fumble on his first carry of the season to get 71 yards in the first quarter and 118 with a touchdown for the game. But he didnt get the ball on second-and-1 from the San Francisco 2 with a chance to tie the score early. Instead, Romo was sacked and Dallas settled for a field goal.
