I'm speculating but, Judson may have been a replacement for a school that backed out at the last minute. Not sure if BW has ever scheduled a NAIA school during his tenure at Bradley.
The only NAIA team that Bradley has played in the last 10 seasons was an exhibition game on Nov. 1, 2017 against Robert Morris University of Chicago-

Robert Morris University merged with Roosevelt University in March of 2020, and dropped the name Robert Morris. Roosevelt is an NAIA school and competes in the Chicagoland Collegiate Athletic Conference, as did Robert Morris until this season. The CCAC is the same conference Judson University plays in.
