Now Wood: I do not see him on the team next year at all. They are paying him too much to be a pen arm. I would trade for a legit closer. Say Pap. there is a connect going.
In regards to Edwards in MR, I'm not that opposed to the idea of a Shark like break into the majors(think the cards did this with both Wacha and Martinez). I'm just saying with their current roster I don't see the room. Roster can obviously change though.
As for wood, he's not making that much. He's making $5.7 mil this year and will be arb 3 next. AFAIK arb never goes down but I doubt he's going to get any raise so for the sake of argument let's say he gets $5.7 again in arb. Motte is making $4.5 mil this year. Additionally, while Wood isn't ideal for the rotation today, you always want to have some wiggle room with 7-8 MLB caliber starters because injuries wreck you. If we assume they have Arrieta, Lester, Hendricks and Hammel as locks for the rotation you could basically toss Wood Pierce Johnson, Jokish, Beeler and Turner in there as competition for the #5 with some ending AAA. Some of those guys probably get knocked off the 40 man but the idea is there.
I'd also throw out the point that as a reliever Wood has a 2.59/3.04 ERA/FIP and happens to be a lefty. My view is you're talking Strop, Grimm, Rondon, and Ramirez for sure. You've got to have at least one lefty in there and many managers like 2. You'd also have the question of closer if Motte isn't back(I was wrong he only signed a 1 year deal apparently). Ultimately, I agree you could use the idea I just don't see it as an amazing fit. Feel free to correct me if I'm wrong here but I believe Shark(and Cashner) were used in 7th/8th inning roles when they were worked in this way rather. If you are maddon why are you pitching Edwards instead of Grimm, Strop, Rondon or Ramiez in the 7th/8th assuming they are available? Now of course there will be days he can pitch because others aren't available and maybe he gets some 4th-6th inning mop up duty too but realistically how many innings is he going to pitch? Seems unlikely he'd get to 70 doing that. Villanueva had that sort of role last year and pitched 77.2 but he also started 5 games which you have to figure is at least 25 of those innings. So maybe we're talking like 50 IP.
I guess to me I'd just rather seem him throw 100 IP in AAA and come up in July/August next year and work out of the bullpen rather than break camp with the cubs and throw less than 70 innings again out of the bullpen. At some point you have to build him up to throw more than 150 innings. In the case of Cashner and Shark, Cashner was 26 before he did it and the following season he had injuries and Shark did until he was 27 which arguably should start to be when you're going through your peak rather than just adapting to being a full time starter. Hell, if Edwards starts in AAA you can have him skip every third start or have him always pitching on 6/7 days and keep him fresh if you wanted to and potentially have him as a starter in July/August going forward. Seems like you have far more options that way.
