To watch it play out on the field, you have to wonder about the brilliant formula or philosophy that's behind it.
But as it turns out, the defensive prowess of Conestoga Valley's girls' soccer team isn't all that complicated, according to Rebekah Krasinski.
"We get along really well as a team," the Buckskins' junior defender and captain said. "And if one of us messes up, we're always there to get each other's back."
As it went again Friday.
Getting the gamewinner from Michaela Horst 26:30 into the match, and a swarming defensive effort that shut down Manheim Township's attack time and again, Conestoga Valley strengthened its hold on the Section Two lead with a 2-0 L-L League Sections One-Two crossover victory over the Blue Streaks in Witmer.
The win gives the Buckskins a (9-0 L-L, 10-0 overall) a comfortable 11-point cushion over Warwick (5-3-1, 5-5-1) in the Section Two race with six regular-season games remaining, and leaves CV as one of only two L-L teams - along with Section Three leader Cocalico (8-0, 9-0) - to be undefeated.
That the Buckskins got to that point by knocking off Section One powers Hempfield, Penn Manor, Cedar Crest and Township, Section Two foe Warwick, and perennial District Three power Central Dauphin, makes it all the more impressive.
"I really believe the toughest stretch of our schedule is behind us," CV coach Pete Shellenberger said. "Honestly, I feel like we're really looking up from here. But we still have a couple of games where we need to keep sharp."
Starting with next Tuesday's nonleague clash against defending PIAA Spring champion Cumberland Valley, which blanked the Buckskins 5-0 in the first round of districts a year ago.
But if Friday was any indication, the Eagles figure to see a different Conestoga Valley team this time around, as Section One leader Township might attest.
Fact is, by game's end, the Blue Streaks (6-2, 6-2) had mustered just three shots against CV's defenders, who limited Township to three legitimate scoring chances.
"Composure, I think, was the real difference," Streaks coach Terry Law said afterward. "Even before the first goal I thought we lost our composure. I don't know if (the Streaks) were hearing footsteps or not."
Some of which, perhaps, might be to CV's credit.
"Absolutely," Law said. "They put a lot of pressure around the ball, and that certainly accounts for a lot of it."
Meanwhile, while Township's defense was successful in limiting the Buckskins to just five shots and four scoring chances in the end, it could do little about either of CV's goals, starting with Horst's gamewinner.
After midfielder Kendra Blantz uncorked a long, centering pass from the left sideline with 13:30 left until halftime, Horst - who suddenly found herself all alone in the center of the box - one-timed a volley that soared over the hands of Township goalie Alexa Rose and under the crossbar for a 1-0 CV lead.
Horst helped double the Buckskins' edge with 4:36 remaining in the first half, when she delivered a cross into the box to Samara Yurchak, who redirected a bullet inside the right post.
And from there, CV's defense took over.
While the Blue Streaks managed to apply some pressure in the second half, aside from Danni Engwall's shot over the crossbar with 32:39 left to play and Taylor Diamon's chip shot over the cross off a corner kick with 2:09 left, it amounted to nothing.
"Someone pressures the ball," Shellenberger said of his defense, "and the others drop back and cover."
That simple, apparently.
