In 2011, UU fans (and even basketball HC Larry "$80K" Krystkoviak) accused BYU of tampering when Josh Sharp transferred from the UU basketball team after his mission, and it didn't matter that Josh and his parents publicly denied the accusations/insinuations, it was canonized in UU fan lore as gospel truth.
And again in 2020 when Caleb Lohner signed with UU but then decided to transfer to BYU, UU fans rolled out the same accusations of illegal tampering/recruiting, except that time they even took it up a notch by saying that BYU had offered Lohner's dad a job in Provo.
This is just the same old crap, recycled from earlier transfers.
