Cubs are stacked in the bullpen. They don't need more bullpen arms. I would be very cautious dealing Marshall. Not too many 6'7 left-handers can throw with control. I love how he keeps himself cool and calm under pressure. First: Just because the Cubs are "stacked in the bullpen" doesn't mean the Cubs bullpen is any good. Outside of Howry/Erye/Ohman, the Cubs bullpen is full of ??? and crappy pitchers. So I think the upside of Wagner is greater then that of guys like Novoa/Wuertz, etc. And I like Marshall, but if the Cubs can fill two needs with one stone, then you do it. Marshall may never be anything more then a 4/5 starter in the majors, and those are expendable. Cubs are a tremendous strength right now in the bullpen. A lot of people forget Dempster was pretty solid with regular work. Kerry Wood, Cotts, the kids filling in, Wuertz. Nothing wrong in the pen.
