I agree with this, but he was great (undefeated?) until he was suspended. In Cincy however, he is "the star", not so in Boston. Also, the Sox have a long history of trading All Stars (I remember the Sparky Lyle for Danny Cater deal.) This could be just the thing for Arroyo's future.
No question, the Reds are going to fall. Just like Baltimore last year. (Full disclosure, I'm a Cub fan too - Love Wrigley and, until 2004, liked my misery each fall in both leagues!) Arroryo can lose 20 in Cincy, but still have All Star stats if he pitches well. I don't think the team matters much in this area.
