My reason in stating "He's black" was racial...but not for the reason you gave.
I believe that there's a reluctance to fire high-profile blacks (such as Chaney) because of the resulting noise from the Jesse Jacksons and Al Sharptons who'll scream "racism" at the drop of a hat.
At the minimum, Chaney should have been roundly punished for his death threat against John Calipari.
Not always...The Orlando Magic canned Doc Rivers. Of course they lost a lot, even with T-Mac when they had him.
Ohio State sh*tcanned Randy Ayers for recruiting the fugitives from the chain gang and creating the resulting legal problems that destroyed their program for a few years.
Of course the Pittsburgh Pirates NEED to fire Lloyd McClendon, but because he sucks as a manager, not because of his color. I could get better production out of their talented young players than he has.....
