I’m not sure about Zach but Jaxon Dart holds the state record for most passing touchdowns in a season. I think he’s also #2 or #3 in pass yards in a single season and the kid who holds the state record is Devin Browne, who was Corner Canyon’s QB the year after Dart.
Corner Canyon’s coach also coached Austin Kafentzis who at one point basically owned all of the passing records in this state so that guy knows how to get the most out of his QBs.
