To be fair to Stone, Harrelson doesn't really offer much in terms of conversational hooks to bring Stone into the discussion.
Stone is very knowledgeable, but I've heard he's kind of a jerk to be around outside the booth.
I personally think they both should go, and the Sox should put a completely new team there.
I used to dislike DJ, but I actually think he does a better job on the radio than he did on TV, so maybe you leave the radio crew alone.
But clearly the TV broadcast needs a major overhaul, especially if they are going to be bad for a few seasons, since Hawk is absolutely insufferable when the team is playing poorly due to his personality and homer mentality.
