I think Taliek was polarizing. He had plenty of us in his corner, and some who would say "see, I told you we can't win with him" every time we lost. There are even some who, after he won a title, pointed to his one off game in the whole tournament (Duke) and said we won in spite of him. He's still picking pieces of Jarrett Jack out of his teeth, and the Alabama point guard had something like two points and two assists in the Elite Eight, but since he had a rough day against Duke, some people think we won the title without him.
I think it's more about a persons appearance. TB had some flaw in his appearance that bothered people. Same with JD.
In Jerome's case it was his constant scowl or aggressive appearance. That "look" is perceived by viewers as being "punk like", whether it is accurate or not. It is inherent in our programming to accept certain physical personas over others. KW's presentation is far more acceptable to people than JD's. Calipari's is far more acceptable than JC's (by neutral parties of course and not the world of invested bb junkies).
We are shocked by a mass murderer who is good looking and well dressed, but not by an unkept individual, even though it is just as likely for a "proper appearing" individual to have this tendency. Again this is because there is a preconceived "bias" within us that gravitates towards an impression, accurate or not.
I have a harder time putting my finger on the aspect of Taliek's appearance that created the blackboard scratching reaction in fans. If I had to guess, it was his the combination of his facial appearance and his speech pattern, both of which combined to make him "appear" uncouth to people.
Like it or not, we form impressions of the physical appearance of people, and label people both positively and negatively, without examining the underlying character of the individuals. And since few of us want to be considered biased, at least in this time period and on a multicultural forum, we look for attributes in the person we hate, or the opposite, the attributes we like, that support our claims and are socially acceptable to discuss.
So the negative focus for Taliek turned on his bad shooting and "out of control" dribbling into the lane, or specific games in which we can label him for a loss. And the negative focus for Jerome, turned on his out of control drives into the lane and turnovers and his suspension and bad season.
One last point and a slight over generalization. The people, for whom JD's appearance brought up the strongest reactions, found it necessary to character assassinate JD, in order to neutralize him. The reactions of these individuals towards JD became personal. It was more than just about basketball and UConn's success. It was a reaction to all their past personal experiences with people in their lives who hurt them and had the same physical persona JD presented. In other words they transferred the actions of their own personal experiences onto JD. We all do this to a greater or lesser extent so I'm not judging the actions and reactions of people in this forum or in society in general. I just think understanding our behavior is critical to understanding societies problems.
