Coming off a 13-win season which ended with a bitterly disappointing playoff loss at home to the New York Giants, the Cowboys lived up to all their preseason hype with a solid all-around performance.
They're the team to beat in the NFC, and after one game, it's hard to argue there's any better.
"We're ready," said Owens, who finished with five catches for 87 yards. "Training camp and all that stuff is over with. The season is here and this was a great start."
With Romo completing 24-for-32 passes for 320 yards, Dallas' offense controlled the clock and strung together four long touchdown drives. The defense held one of the AFC's most potent offenses in check, and except for some silly penalties, the star-studded Cowboys had a dazzling debut.
"We faced a good football team and made them better," Browns coach Romeo Crennel said. "We dropped balls, missed tackles, missed an interception and let them throw a (touchdown) over our heads. You can't do that and expect to win. A lot things went wrong."
The Cowboys, who led 21-7 at halftime, had touchdown drives of 80, 69, 69 and 86 yards, the final one capped by an 11-yard TD run by rookie Felix Jones on his first regular-season carry. He finished with 62 yards.
In the second quarter, Owens blew past safety Brandon McDonald and hauled in his TD pass from Romo to give the Cowboys a 14-7 lead.
One of the league's most celebrated end zone showmen, Owens placed the ball near the goal line and shook each leg as if he was getting ready to get into the starting blocks and take on Olympic blur Usain Bolt in the 100 meters. He was called for unsportsmanlike conduct.
It was his 130th career TD, tying him with Cris Carter for second on the career list behind Jerry Rice (197).
Jason Witten added six catches for 96 yards and Barber rushed for 80 on 16 carries before leaving in the third quarter holding his ribs.
Dallas head coach Wade Phillips said he's a "little worried" about Barber's injury but wouldn't speculate on the severity or if the running back will be ready for Philadelphia next Monday.
Cleveland's only touchdown came on Derek Anderson's 2-yard pass to Kellen Winslow in the second quarter.
Anderson went 11-of-24 for 114 yards but never got into a rhythm with wide receiver Braylon Edwards, who had only two catches.
