Not surprised in the least - Midwesterner's dominate the sportscasting, announcing, and play by play business due to the flat unaccented voices. The B1G's media market covers NYC (Rutgers) - the DC-Baltimore megalopolis (Maryland) Chicagoland (Illinois, Northwestern, Purdue) Detroit (Michigan)-MSU Minneapolis-St. Paul (Minnesota) Columbus (OSU) plus Philadelphia & Pennsylvania (PSU) Indiana, Wisconsin, Iowa and even Nebraska. They represent a significant swath of the US population and a large portion of the ESPN - CBS audience. The bias is rooted in revenue.
