I recently came across a re-run of ESPN's "30 for 30" episode entitled "I Hate Christian Laettner". For those few of you who don't recall, Christian Laettner was the 6-11 Duke men's basketball player from the early 90's who was thought to be one of the best college players of all time when he played at Duke. He also was white and had a Diana-type personality that made him easy to hate, particularly when his Duke team beat other teams like the Fab Five and UNLV. Although he was from a very middle-class family (not really "privileged" as most people think of Duke students), and was never involved in any off-court misbehavior, he was seen as emblematic of the privileged preppy who could never win any sympathy, even when his Duke team was the underdog in terms of talent to many of the teams that they played.
Right after he graduated in 1992, he became the sole member of the US Olympic team who did not yet have NBA experience. He was chosen for that role over Shaquille O'Neal. Does that remind you of Stewie?
I think that is what Chiney means by "hate" -- the hate reserved for people or teams who succeed after being privileged, as opposed to those who succeed by emulating David against Goliath. UConn WCBB will always be Goliath, and who ever roots for Goliath to win? This is true even in cases such as last year, when UConn was not Goliath in its talent level as compared to other elite teams. The fact that UConn beat so many other elite teams despite its seemingly inferior talent certainly contributes to its Goliath image, with all of its negative and "hate-able" aspects.
But really, that kind of "hate" is a compliment, and should be viewed as such by the players and coaches who have earned it.
