"Because of the press, it was able to up our tempo and get into transition more," added Vitelli, who scored a game-high 17 points.
Several Falcons attempted to dribble through the press, only to get trapped near the sideline. Other times, Pennsbury (4-4) tried diagonal passes or threw a long ball down one-third of the court, resulting in frequent turnovers.
Picks were set and players moved off the ball, but the Falcons just couldn't figure out how to get past the pressure of the Titans (7-2).
"I think it was more on the defensive side than anything," said Mosher, who finished with 14 points. "We really just shut down their key players and were just really being active on the ball."
In addition to struggling against the press and shooting poorly from the field, the Falcons were hurt when their best offensive player, senior Sajanna Bethea, got into foul trouble.
Bethea was consistently one of the few Pennsbury players able to penetrate the lane against the Titans. But she had three fouls before the first half ended and eventually fouled out in the fourth after scoring nine points.
The Falcons will look to get back on track with games against five straight National Conference foes. Meanwhile, the Titans have a big task ahead of them, as they will face Continental Division rival Central Bucks West on Tuesday.
"The pressure is on, knowing we have West on Tuesday," Vitelli said. "We wanted to make sure that we didn't lose any games that we shouldn't."
