The Whittinghams were the only other Provo kids I’m aware of.. I’m sure there are a couple others but they’ve been fairly rare from the PHS boundary.
Again the vast majority of players have come from within during the 20 year with the core being the multi brother families- Kaufusis, Reynolds, Covey’s, ashworths, badgers, van Leeuwens amongst others
Xavier and Gabe Reid were the two big out boundary guys but obviously they don’t want to play for garbage programs in AF and PG and came because of the program that was established by Van Orden before transferring was even a thing.
Then obviously there were a bunch of other outside guys too but not as many as people think.
