There were stories about Eric B while Eric was a player at CU Boulder. Then Eric was a coach at CU. More stories about emotional abuse by Eric towards the black running backs. Called them girl names and was disrespectful in general. Eric does not have a perfectly wonderful reputation as a player nor as a grown up in the state of Colorado.
As I said on another thread about this, maybe Bienemy doesn’t interview well. Maybe he is not cut out to be a head coach (many coordinators fail to make that leap). Who knows? Maybe he doesn’t want to go to a team in the same division as the Chiefs? WTFK? But any owner in the NFL would hire anyone - white, black, polka dot, transgender - who could bring them a winning team.
