I think Hawk ran out of interesting things to say about five years ago. It's probably more a testament to his long tenure in the booth than anything else, but almost all of his baseball insight is stuff we've heard before. He does invent a new Hawkism every once in a while to keep things fresh, and if you're lucky, an ump will make a bad call and Hawk will go off for an inning.
Otherwise, give me DJ and Singleton any day of the week.
