Scott came from a background of working with tennis and, as I recall, got US women's tennis on an equal pay scale with men's, not by lowering the payout to the men, but by helping raise the profile of the women's game.
Yormark was working with NASCAR when it moved from a regional brand with a smattering of following outside of the south to a national brand. Then he went to ROC nation, Jay-Z's company, that was involved with an array of media related productions and contracts.
Scott tried to innovate by creating a conference network that would be owned exclusively by the conference. He spent like his hoped-for projections were guaranteed. It was a colossal failure. And he refused to pivot the entire time he was commissioner.
Yormark has an attitude of partnering with other media providers and creating win-win scenarios. Like NASCAR, he wants to expand the footprint of the Big XII. And he wants to expand it in terms of entertainment offerings, not just geography.
I can totally see why Scott seemed like the right hire at the time.
Yormark seems like a total home run. Beyond what the PAC 12 could have realistically hoped for with Scott even in the beginning.
