Class and sportsmanship are aspects of right and wrong, and right and wrong are all about whether one will do something that's possible, advantageous and without negative consequences for them--but still wrong. People keep confusing enlightened self interest with morality, but the latter involves a sacrifice for ones beliefs. No one will convince me they "did the right thing" if they knew they'd profit; that's a "business decision" in which morality is as relevant as goldfish are. As much as I loathe Vince Lombardi for many things, the story goes he tried that QB sneak in the Ice Bowl because he found the mental image of both teams playing OT after a FG too objectionable, and, if true, I have a lot of respect for that. Of course, I've also heard that, when told after the game that some of the Cowboys had frostbite, he said, "Losers get frostbite" and the two stories are mutually exclusive.
