We have had a quite a few years where two teams had two state champs. In many cases the two from the same school bring within a weight or two of each other. Good practice partners help.
But 2003 has to be the last I can think of with 3 or more champs from more than one team. Griffith with A. Escobedo, Hernandez, A. Tsirtsis three in a row. And then a couple weights later EMD with weinzapfel, Nosko, Wildeman, Mauer four in a row.
Somewhere around 2012 or 2013 I believe Perry Meridian had 3 champs. Whenever it was Donte Windfields Senior year. That maybe the last time one team had three champs.
