Cowherd is from the Northwest and started his career really in Vegas, so I will give you that Left Coast bias. Golic is a Damer, so it surprises me you think he is a Big 10 homer. Herbstreet I can see since he went to OSU but he usually downplays his OSU ties and kisses Michigan's butt to much in an attempt to be partial. Greenie, well he went to Northwestern but has never put on pads, so I don't know how that plays out to a Big 10 bias since they only play well once every 10 years.
I've have always thought they (Entertainment Sports Programming Network) always featured SEC and ACC teams even though the ACC hasn't been good in years if not a decade. The SEC I can see, but not the ACC unless you are talking B-ball.
All that being said, the Pac 10 was legit this year with USC, Cal, Oregon (before Dixon goes down), and ASU. Big 10 was soft and OSU can possibly Luckeye another championship by backing into the big game. But then again LSU is in the game with 2 losses, so it has been a very unusual year. I would like to see a 16 team playoff and college football would own late December like college basketball owns the March TV ratings.
