Is jeff samardzija this years version of carlos marmol?

Last year for the cubs when the bullpen was a major mess, marmol came up from the minors and provided major relief for the rest of the season. Now this years cubs bullpen isn't nearly a mess as it was last year, but you have wood on the DL, howry having a terrible year, and the only other 2 relievers the cubs can trust are marmol and cotts, both of which are very inconsistent. I think, if anything, samardzija can provide some stability and some needed depth in the bullpen.
