It was tough to tell in yesterday's Maryland Scholastic Association A Conference football matchup whether Gilman's defense was playing that well or if Calvert Hall's offense was playing that poorly.
It was probably a little bit of both.
What was easy to understand was the outcome, a 13-0 victory for home-standing and third-ranked Gilman School.
"We played four solid quarters this week for the first time all year so it's a nice win for us," said Gilman coach Sherm Bristow. "I'm really proud of our defense because they've been playing well all year.
"We saw Calvert Hall shred a couple of teams, and we knew they could run the ball well and that they have some passing weapons but we're a solid team and we beat a very good team today."
Calvert Hall, which entered the game 4-0, was held to nine yards of total offense in the second half and gained a total of 57 yards and three first downs on the day.
Not exactly the kind of performance Calvert Hall coach Bill Mackley was expecting from his senior-laden offense.
"I probably would have bet my house that we were better prepared than we were today, but it just goes to show what can happen when you go up against a real good football team," Mackley said. "They played more aggressive than we did on the line of scrimmage."
After a scoreless first quarter in which both teams struggled to move the ball beyond midfield, Gilman put together a 12-play scoring drive that covered 64 yards. Senior running back Jim Zimmerman capped the drive with an 8-yard touchdown run and Mike Allan added the extra point to give the Greyhounds (5-0, 2-0) a 7-0 lead with 9:46 remaining in the half.
Gilman got the ball back with 36 seconds left in the half and quarterback Mark Cornes executed the Greyhounds' two-minute offense to perfection, setting up a 31-yard field goal by Mike Allan.
Neither offense could pick up a first down on its first three possessions of the third quarter, but Gilman finally got something going following an interception by Peter Bogue.
The Greyhounds took over at their own 37 and drove the ball 53 yards on 14 plays before Allan added his second field goal from 27 yards out.
As if things weren't going bad enough for the Cardinals, they were dealt an additional blow when quarterback Dennis Grinestaff injured his knee while playing in Calvert Hall's secondary.
The Cardinals didn't have any more luck with backup Tom Soltis calling the signals. Soltis managed to complete a 12-yard pass to Dominic Liberto before throwing an interception to Terrance Whitehead.
