I've been able to watch barely any games this year, so it's hard for me to get a perspective on Morgan's problems. I'm inclined to think that he will come back around, once either his shoulder gets better if it's still bad, or he simply sorts out the mechanics of his swing, which seem difficult to maintain. But most people here (who have watched him much more than I have) seem ready to give up on him completely. He was having a great year for a while there- is he really that hopeless?
Obviously if Morgan can get going again the lineup would be improved immensely.
