Leagues or tournaments?
Gotta think that with contact camps being essentially abolished that passing leagues will become much more prevalent on a weekly basis.
San Leandro and Monte Vista do a weekly passing league during the summer. Foothill always has an excellent passing league tournament the 1st or 2nd week of June.
Los Medanos College puts a good one one that usually has Pitt, Clayton and De La Salle in it. Usually end of June. Liberty coaches said this year it's on the 27th.
