Havig a healthy Bobby Crosby will be crutial to the success of the A's this year. Crosby has a world of talent. Although his achilies heel is his violent swing. I believe that if the A's want to have Crosby on the field for the good part of a season they will need to retool his swing. With Bobby's previous back injuries his body simply cannot take his swing. I know what people will say that there is no way that a major league player can change his swing midseason or when he is as old as crosby is. If Cosby does not change his swing in my opinion his career will be spent on the Dl. That being said I hope that Bobby will prove me wrong and have the kind of season that he is capable of having.
