Piaa puts all 7 of the district 1 teams on the same side of the bracket for state playoffs just so a fake team can play for the championship. All 7 district 1 teams would beat the non-district 1 team that makes the finals.
the part of your quote that I bolded is inaccurate.
In Class AAA, D1 qualifies 6 teams for States, while in Class AA, D1 qualifies 3 teams for States. (The number of qualifiers gets reset every two years. It appears that for 2019, in 2A D1 will only send 2 teams to States.)
in last year's boy's PIAA 3A bracket, 1-2 (Avon Grove), 1-3 (Garnet Valley), 1-4 (CB East), 1-5 (Spring-Ford) were in the top half of the bracket, while 1-1 ('Stoga) and 1-6 (Haverford) were in the bottom half of the bracket. In last year's PIAA 2A bracket, 1-1 (Springfield) was in the top half of the bracket, while 1-2 (WC Henderson), and 1-3 (Strath Haven) were in the bottom half of the bracket.
2017 was the 1st year where there were 2 classes in boy's lacrosse. In 2016, D1 sent 5 teams to States, with 1-1, 1-2, 1-3, and 1-3 in the top half of the bracket, and 1-5 in the bottom half of the bracket.
The overall point of your statement is correct. The D1 teams do generally dominate LAX (both boy's and girl's) in the PIAA, and there is frustration in D1 that they are mostly on the same half of the bracket. If I recall correctly, for boy's through 2014, D1 teams had only 4 loses in States to teams that were not D1 or D12 (Philadelphia and Philadelphia Catholic League, which includes some suburban Catholic teams). At that time, Manheim Township and Emmaus (2 times each) were the only non-D1 or D12 teams that had beaten a D1 team in States for boy's LAX.
