Ok, being off last week, I admit I haven’t been paying the closest attention. But can anyone explain what exactly John Calipari means by these “Radio Silence” tweets? First thought the Kentucky basketball coach was lashing back at his critics, or at least three of his critics — thus the “triumvirate” comment — over something. But now Cal has tweeted that he’s talking about twitter. And what does this have to do with “radio” silence? Color me confused.
