The "C" Word Controversy

if Jeremy Lin had been losing games for the Knicks, and the phrase "chink in the armor" had been applied to the Knicks, that could legitimately be considered a racist pun. However, as he's been winning, and the phrase was applied to HIM, interpreting it as racist doesn't make any sense: "Jeremy Lin has a chink in his armor".... how is that racist? The MSG remark was racist. The "Lin Dynasty" joke probably had Lin himself smiling with pride.
