Because ESPN pushes the SEC so hard? Oklahoma obviously has been crushing it lately, but if you look at the entire history the Pac has absolutely owned softball. ESPN decided out of pretty much nowhere based on nothing that the SEC is THE power in softball. So us West Coast fans have been enjoying watching the SEC's disastrous performance the last 2 years.
Probably also, pretty much everybody outside of SEC country has a very healthy dislike for the SEC in general, and in particular football, that spills over into most sports. Especially if ESPN pushes it hard (I know, they have a contract w/ the SEC, so of course they are going to hype the conference, but it doesn't make it any less annoying).
