First, comparing Mayfield at number one overall to Terel Bernard is pretty funny but lacks logic.
My original quote citing draft results was from 2017. Although Beane wasn’t here, it is certainly a given that the current “regime” started then. Why wouldn’t you start by picking any other team in the NFL and listing their first round picks since then? If Beane has been the failure that you claim, you should EASILY be able to pull 10 or so teams drafts since then and compare. Our average slot for these 7 picks was 19.2. That also comes into play. Your assessment of both Oliver and Elam is also way off but maybe that is for another thread.
