There were people saying it at the time too, FWIW. It is too soon to say though - Payton has a nice role as the backup at NDSU, but honestly by looking halfway competent against Michigan Haarberg has a huge early lead.
Looking back, none of the 2021 QBs we had a even a small shot with (Jake Garcia, Dematrius Davis, Peter Colstelli) have really panned out anyway. All these 2021 guys are showing up now though - Wimsatt at Rutgers, Kaliakmanis at Minnesota, Deacon Hill at Iowa, Altmeyer at Illinois, Sheduer at Colorado, and Haarberg were all between 25-40 ranked QBs in that class. Sanders is the only one who has shown more than flashes, and several have transferred. In retrospect maybe we should have checked out that Riley Leonard guy (58th ranked).
