I have no way to know although I’d bet trinnaman, who I’ve watched since he was in HS is a legit sub 4.4
And you’re wrong about the Utes, dozens might be an exaggeration but only slightly, in fact they are a running joke with their reported pro day 40 times. They’ve get multiples this year they are claiming at 4.4 and faster.
And if you care to actually read my post I said “sub 4.5” in reference to BYU. You don’t think they’d have two or three guys per year that run 4.4’s? Of course they do.
