Rapid Reaction: Lions 34, Cowboys 30

ARLINGTON, Texas -- The Cowboys blew a 24-point lead, the second time this season a double-digit second-half lead was blown resulting in a loss. Detroit 34, Dallas 30.

What it means: The Cowboys head into the bye at 2-2 and missed a chance to take momentum into the game against New England in two weeks. It was a bad loss, possibly worse than the Week 1 loss to the New York Jets. The Cowboys were booed when they walked off the field. This was terrible.

Romo's screwups: Tony Romo's three second-half interceptions led to three touchdowns for the Detroit Lions. The last turnover was on a pass to Jason Witten that came with 4:13 to play in regulation, and the Lions took the lead on the ensuing drive. In Dallas' Week 1 loss to the New York Jets, Romo committed two turnovers in the fourth quarter. You can't have that if you're trying to be an elite quarterback.

Johnson's day: He didn't have a catch in the first quarter, but as the game picked up, Calvin Johnson turned into Megatron. Johnson finished with eight catches for 96 yards and two touchdowns, including the go-ahead score with 1:49 to play. The Cowboys' secondary struggled to cover him in man and zone coverage. The last score was a jump ball over Terence Newman. Rob Ryan said Dez Bryant and Miles Austin were better, and Jason Garrett said Johnson was the best player in the NFL. Looks like Garrett may have been right.

Where'd Dez go? After catching three passes -- including two for touchdowns -- in the first half, Dez Bryant was shut out in the second half. Bryant played with a bruised thigh but still was effective, catching touchdown passes of 25 and 6 yards. But with the Cowboys turning the ball over and running the ball, it made Bryant ineffective on the day.

What's next? A bye. The Cowboys take four days off and will get ready for a trip to New England in two weeks.
