How, I understand your point. However, I do not view it the same way. All of us who played sports up through high school had coaches come and go, and that was accepted. Having that take place now is not a cultural change. However, the idea of a player deserting his team was a different deal...particularly if you deserted your team just before the playoffs (which is the nearest comparison I can make to leaving before a bowl game). Sure, if we believe that in the current environment all college players are now professionals, then the same rules don't apply from a legal perspective. But culturally, I think 95%+ of fans probably view bailing on your team before a bowl game to be a betrayal of your team mates, because that is how it would have been viewed had we done the same. I don't like the idea of bailing out if the kid is going to the NFL draft, but I've learned to live with it. For a kid who is not going to the NFL, however, and is simply blowing off his team to go play elsewhere, I doubt that I'll ever find it acceptable. And I don't think I am alone in that.
Fundamentally, as things presently stand, college kids are permitted (heck, they are encouraged) to behave like mercenaries. I'm not sure how the marketplace will respond to that...if only 10-20% of the fans are turned off to the extent that this is the straw that breaks the camel's back, then the revenue impact on college sports will be devastating. The whole pageantry, tradition, rivalries, league structure, etc., aspect of college football is badly wounded and may not survive. There don't seem to be many adults in the room when it comes to foreseeing how this will impact broadcast eyeballs, gear purchases, event attendance, and all the other stuff that ends up paying the bills. To those who say, "It's a business", I respond that that was what the geniuses at Coca Cola said when they replaced old Coke with new Coke. I'm not sure that the college football market will survive the replacement of "old college football" with "new college football" without a lot of casualties.
