Chink In Armor
1) An narrow opening and vunerable area in one's armor that the opponent will usually aim for. This term relies on "chink" in the sense of "a crack or gap," a meaning dating from about 1400 and used figuratively since the mid-1600s.
2) A figurative term for a one's weakness, largest flaw or their prevention of success.
Jeremy Lin himself accepted the apology, said himself that he did not believe it was the intent of ESPN or the people involved to be racist in their question. A cursory Google search would show that the term "Chink in ones armor" was and is not a racially charged statement, and has a long history that has nothing to do with one's ethnic heritage. ESPN was correct to apology for not realizing that the comment when applied to Jeremy Lin could be misconstrued, but ESPN was and is wrong in their firing of the employee, is wrong in suspending one of their announcers.
Maybe the time has come where people need to relax a little bit, need to stop looking for slight and attack where none was intended.
