PORTSMOUTH - If there was a "what if" for the Chesapeake Panthers, they never got to find out what it was.

Early mistakes helped Portsmouth jump to a big lead and the Trojans went on to beat the Panthers 47-6 Friday in the season opener for both teams.

"We probably should have had a score in the first half, and we made a coverage mistake that gave them their score right before the half," Chesapeake coach Phil Davis said.

"I'm not taking anything away from Portsmouth. They've got a nice team and they deserved to win, but I thought we could've done a better job. We let it get out of hand."

The score right before the half was a 49-yard pass from J.R. Glockner to Justin Nelson. Drew Throckmorton's conversion kick made it 21-0 with just 55 seconds on the clock.

"That was a real momentum swing for them," Davis said.

Portsmouth scored late in the first quarter on a 10-yard run by Tyler Clifford. Throckmorton kicked the first of five extra points and it was 7-0.

Andrew Newman ran 6 yards for a touchdown and it was 14-0 with 9:35 left in the half, and then came the quick score with time running out.

The Trojans blew the game open with three touchdowns in the third quarter. Glockner hit Clifford down the middle of the field on a 20-yard pass play for a score, Newman ran 5 yards, and Michael Purdy returned a punt 59 yards for a touchdown with 5:01 on the clock to make it 41-0.

Chesapeake avoided the shutout with a 7-yard run by Terry Brown with 8:36 to play.

Portsmouth finished with 305 total yards with 157 on the ground and 147 through the air. Newman ran 14 times for 81 yards and Glockner hit 7 of 15 with an interception.

Chesapeake had 90 yards rushing and 28 through the air for 118 total yards. Mike Stapleton ran three times for 32 yards, Kersten Harris got 24 on eight attempts and Mark Roby had 22 on six tries.
