Strange, because there was only one other TE in the incoming class (Tucker Ashcraft) and Booker committed weeks after Ashcraft anyway. Grant Stec is a '24 recruit & a good one, but Booker committed after Stec announced, too. It could be an NIL thing, but UCLA (his rumored destination) never seemed to be pushing hard for him that I know of.
I heard something second-hand that his folks are Badger fans & pushed him into a decision he didn't want to make. That would be my guess.
