In terms of highest ceiling you have to go guzman, marmol, marshall. However, if you're talking likelihood to achieve that ceiling, you have to say marmol, marshall, guzman. Overall, I would say marmol, guzman, marshall. I think if a starter gets injured this year then marmol should be the first to replace him. I see him as a long time starter, not a reliever. Guzman on the other hand could be a lights out closer. Speaking of closers, why haven't I heard anything about Gagne to the cubs. I can't rely on dempster another year. Back on task, i doubt the cubs will put their former number 1 prospect into the bullpen. I can see him having a liriano like year next year after helping the bull pen and getting spot starts this year. However, i can also see him getting injured for a large portion of time like liriano. I agree with the few that say we should trade marshall cuz i think his value right now is as high as it will ever be. So if he will allow us to improve at second, short, centerfield, or will bring experienced reliable pitching then i say trade him.
