I certainly think Marty has been a little too bitter at times but give me his style over Grande/Welsh any day. I was watching the game with my girlfriend last week and she asked me "How come those announcers keep making so many excuses?" I just shook my head and laughed. I can usually only tolerate the Grande/Welsh excuse for every Reds mistake style for about a half game before I just have to go do something else or turn down the volume.
Now Marty has certainly gone off and acted above people before, but his bitterness towards the way the Reds are playing is certainly much closer to how I've been feeling about the Reds. I love turning to my dad or a friend when we're at a game and someone messes up big time and saying "Man, I wish I could hear what Marty is saying right now." The guy isn't afraid to go off on someone when they do something dumb and in today's overly nice culture it's refreshing. And the Reds have certainly been painful to watch. If I were on air being forced to watch and describe every game I probably would have been kicked off the air by now for using too many 4 letter words.
