Larry Scott was interviewed by Bloomberg's Dominic Chu on PAC-12 Networks.

Scott discusses revenue sharing, "equity", and talks media markets. He points out that the "two LA schools" are in the biggest media market.
I'd like to point out that USC, UCLA, Cal, and Stanford are likely responsible for a lionshare of media money because the LA market and the SF/Bay Area media markets are cumulatively larger than nearly any other sporting event in the US except for SuperBowl or Conference championships (provided large media market teams are playing)
This video shows Larry Scott's business perspective on negotiations and revenue sharing.
I'd like to point out that the behavior of NCAA recently has been decidely against the interest of the PAC-X/12 interests because USC and Oregon came under fire, ironically by a NCAA leadership spotlighted by university presidents from Washington and Oregon State.
