What bothers me most is the deceit. Pac-2 looks for safety by scheduling with the MWC, agrees to a no poaching clause, and later sues to void the restriction. To me, bad faith. I'd be surprised if there wasn't some level of collusion amongst the "traitors" and the Pac-2 from the beginning. It's been hard for me not to feel that MWC got "played" by an unscrupulous Theresa Gould and desperate/angry OSU and WSU but who knows. Maybe Gloria Nevarez did all she could to entertain the Pac-2 and defend against the inevitable. To me, this isn't just about a contract dispute...how many widgets were delivered at what price and on what terms. There is arrogance, deceit, and collusion. There is also the irony of OSU and WSU being screwed by departing members...but caring less about who got screwed as remaining members of the MWC. Hypocrisy 101.
Hate is a strong word. You'll have to ask yourself why it doesn't resonate with you at higher level. But I don't wish a single good thing for programs like CSU, SDSU, BSU, USU, etc. Also, I am a little embarrassed at what the MWC has become (with Gloria Nevarez pretending "this is better!"). I cannot fathom NIU (no disrespect at all) being a MWC team (or Toledo or any other school from the Midwest). I like regional rivalries and many years ago, used to think how cool a conference with Colorado, Nebraska, BYU, Utah and the MWC teams would be (minus Hawaii due to travel). That ain't going to happen.
To answer your question, maybe the "hatred" and "vitriol" that people feel is a sense that something important to them is dying right before their eyes. All of college sports pretty much sucks. Maybe it already died for you and you just don't realize it.
In any case, screw CSU all day long.
