last season, when ron santo had a leg operation, the best broadcasting duo hit the chicago radio airwaves... pat hughes and steve stone. hughes can lull you to sleep with his voice, however he's got the gift of gab, which is helpful to paint pictures of what just happened and also to fill in the lulls of the game.
steve stone is one of the best colors i've heard, bar none. he knows what is going to happen and why, but he doesn't really let it dictate his on-air personality. sure, sometimes he can come off as smug and aloof, but on the other end of the spectrum, he ensures that you're going to get a good dose of baseball knowledge when it's all said and done. he's usually paired with chip caray, who is an annoying under-intelligent quasi-cheerleader announcer (but sometimes he acts stern when he tries to mildly criticize the cubs, as steve stone will tell it like it is when its his turn up, whereas joe carter always delved off into left field so chip could get away with being a homer)
nevertheless, the combination of a knowledgeable radio voice and a killer color man is what did it for me.
morgan = annoying, mainly because i've experienced quite a few games with him, and he really lets his knowledge-related ego come into play. mccarver = annoying, but there because he can relate to the lowest denominator non-baseball guy audience that fox is trying to reach, as the hardcores will watch irregardless. joe buck is like chip caray, or vice versa.. he's just more of a national guy. i think chip caray would like to be where joe buck is someday.
