The tradition reaches all the way back to the 1940s.
It really picked up steam in the 1970s.
And it shows no signs of waning in the 21st century.
The York-Adams League is a bona fide boys' volleyball hotbed.
In fact, at the state high school level, there's little doubt that boys' volleyball is the local league's single most successful sport.
That point was proven again over the weekend when Northeastern claimed its fourth state boys' volleyball championship with a 25-15, 23-25, 25-22, 25-22 victory over Ambridge in the PIAA Class AA title match at Penn State's Multi-Sport Facility.
It was Matt Wilson's second state title as the Bobcats' head coach, joining his 2010 title team.
The Bobcats' PIAA prowess, however, actually started back in the 1990s, when they won back-to-back state crowns under Tom Beakler in 1992 and 1993.
But Northeastern is not the only York-Adams boys' program to make its mark at the state level -- far from it.
Central York has collected five state championships, including its most recent one in 2011 under Head Coach Brad Livingston.
Before Livingston, the Kollers (Bruce and Barb) won four state crowns (1975, 1977, 1982, 1985) with the Panthers.
And New Oxford also claimed a state title in 2005.
If you're counting at home, that's 10 state boys' volleyball championships for the York-Adams League since 1975.
That's pretty impressive stuff.
But it doesn't stop there.
Central York, if you include its predecessor, North York, also has claimed six runner-up finishes in state action (1948, 1949, 1984, 1989, 1997, 2008). Spring Grove twice finished second in the state (1954, 1999). York Suburban (2012), Northeastern (2007) and Dallastown (1990) each own one second-place finish.
That's 11 runner-up finishes for boys' teams from the local league.
There's no denying that Central York and Northeastern are the dominant boys' programs in the local league. But if you look closely at the schools mentioned above, you will notice that six different teams from the local league have finished first or second in the state playoffs at least once since 1990 alone.
That's pretty remarkable for a league that includes just 12 teams overall. It shows the depth of quality programs in this area.
Much of that credit has to go to the league's coaches -- folks such as the Kollers, Beakler, Wilson and Livingston -- who have provided the foundation for success.
The talented, hard-working athletes, of course, also deserve tons of praise. So do their parents, who made serious sacrifices in terms of time and money to give their children the best possible opportunity to succeed.
And don't look for that success to stop anytime soon.
Next year, Livingston returns a number of key performers from this year's team, which reached the state AAA quarterfinals.
The same goes for Wilson's Bobcats, who lose just two starters to graduation.
In fact, Wilson believes Northeastern and Ambridge, which loses just one starter, could meet again in next year's state AA title match.
"I think both teams could very well be back here next year if they do what they're supposed to do," Wilson told The York Dispatch after Saturday's finals. "I think there's a good chance of that. I'm very certain that they'll be back, but hopefully we can find a way to get back here again."
If history is any indicator, it would be unwise to pick against Northeastern. The Bobcats have proven they are consistently among the state's top programs. The same goes for Central York.
And who knows, another York-Adams team may emerge to make noise at the state level. It's happened before, and it will almost certainly happen again.
The York-Adams boys' volleyball programs have made a habit of state success.
It's a tradition that's likely to continue for years to come.
