While Brandon Beane does deserve some criticism about his recent draft classes, he has certainly brought some severely underrated players to Buffalo over his tenure. His only true 1st-round superstar that he has drafted is of course Josh Allen. However, he has done well outside the first round.
In his tenure, Beane and the Bills have drafted players like James Cook, Christian Benford, Spencer Brown, and Taron Johnson all outside of the first round. This past NFL Draft back in April, the Bills got themselves a huge steal with drafted defensive tackle Deone Walker out of Kentucky.
