UNIVERSITY PARK – It was billed as the Clash of Champions, but it was a ton of turnovers that sank Southlake Carroll in a 29-21 loss to Florida power Miami Northwestern before 31,896 at SMU's Ford Stadium.

Three interceptions and two lost fumbles also cost Carroll its 49-game winning streak, which was tied for the all-time record among Texas' largest classifications.

Even the game's biggest play, a 75-yard touchdown catch by Northwestern's Tommy Streeter, was taken from Carroll.

Streeter was all alone on the right sideline when he hauled in the pass for the only offensive score of the second half.

"That play, we got from Southlake Carroll," Northwestern quarterback Jacory Harris said. "We ran it against our defense a bunch of times this week because they run it so much. So we decided to go ahead and use it ourselves."

Streeter was the one standout on Northwestern's talent-laden roster that Carroll couldn't keep up with. Streeter caught four passes for 140 yards and three touchdowns.

Another uncharacteristic mistake by Carroll, a deep snap that sailed over punter Loarn Hinkle's head, gave Northwestern a safety and an eight-point lead.

After the safety with 4:41 left in the third, Carroll's last three possessions ended in a missed field goal that hit the crossbar, a fumble in Northwestern territory and an interception on third-and-21.

"Offensively, I was disappointed that we didn't execute in clutch times," said Carroll coach Hal Wasson, who lost in his second game since replacing former coach Todd Dodge. "I'll take the blame for that, and we'll work on that."

Carroll (1-1) lost its first regular-season game since a 17-14 loss to Fort Worth Boswell on Nov. 9, 2001.

Northwestern (3-0) held Carroll to its lowest scoring output since a 16-15 loss to Katy in the 2003 Class 5A Division II championship.

Northwestern lost three fumbles, but none were in the second half, when its defense shut out Carroll.

"We did a great job of making an adjustment at halftime of using an extra defensive back and getting pressure with four guys," Northwestern coach Billy Rolle said. "It worked for us."

It was a made-for-television (ESPNU) matchup of state champions from two football-crazy states. Carroll is the defending Class 5A Division I state champion, and Northwestern is Florida's defending 6A champion.

Carroll came into the game ranked No. 2 in the National Prep Poll, and Northwestern was No. 3. However, Carroll was No. 1 in the USA Today rankings, and Northwestern was ESPN's No. 1 team.

The teams fought to a 21-21 standstill in an entertaining first half. Carroll scored on the opening drive with Riley Dodge hitting Chris Brainard for a 35-yard score. Northwestern's Harris, who was 21-of-28 passing for 282 yards, answered with a 32-yard scoring strike to Streeter.

Carroll linebacker Derek Tomlin returned a fumble 32 yards for a 14-7 lead, but Harris answered again with a 19-yard touchdown to Streeter. Another Harris touchdown pass was matched by another Dodge touchdown pass, a 26-yarder to Blake Cantu.

However, Carroll blew a golden opportunity just before intermission. Running back Tre' Newton caught a pass out of the backfield and rambled 23 yards, but he fumbled at the Northwestern 6 yard line with nine seconds left.

Carroll tossed away another opportunity on its first drive of the second half. With Dodge sidelined temporarily with a bloody nose, backup quarterback Kyle Padron drove Carroll to the Northwestern 24. However, Northwestern's Khalid Marshall picked off Padron in the end zone to end the threat.

"We've got to drop it now, because we've got a game Thursday [at Rockwall]," said Dodge, who was 22-of-29 with two interceptions.

WHAT WENT WRONG

Here are key plays that hurt Southlake Carroll in its 29-21 loss Saturday to Miami Northwestern:

Interception costly: Northwestern's Sean Spence intercepted Riley Dodge's pass at Carroll's 44 and returned it to the 19 early in the second quarter. Two plays later, Jacory Harris hit Tommy Streeter with a 19-yard touchdown pass that tied the score at 14.

Big first downs: Northwestern's Aldarius Johnson made a couple of third-down catches on his team's second scoring drive of the second quarter. The second one, a 16-yard TD catch, put Northwestern ahead 21-14.

Red zone fumble: Carroll linebacker Brayden Burnett recovered a fumble with 31 seconds left in the first half and the score tied, 21-21. But Tre' Newton, hit hard at the end of a 23-yard catch and run, lost a fumble at Northwestern's 6.

End-zone pick: With Dodge out of the game after being hit on the nose, Carroll drove to Northwestern's 24. But Northwestern's Khalid Marshall picked off a pass in the end zone, and Northwestern scored two plays later to go ahead to stay.

Bad snap: A snap sailed over the head of Carroll punter Loarn Hinkle. In an attempt to prevent Northwestern from getting the ball and scoring a touchdown, Hinkle kicked the ball out of the end zone for a safety, and Northwestern went up, 29-21.
