I think there is real merit to this idea IF, and probably a very big IF, Kubel can regain his stroke. When healthy, he's always had a nice swing and power, and while not great range, in his previous time with s his glove was OK and his arm pretty good, so he could provide a little corner OF play on occasion.
However, making a complete turn from my potential agreement with Dave is that Reynolds is RH. I truly feel we need to sign someone who can play sme 1B, 3B, PH and maybe even DH on rare occasions from the left side in the INF.
Once again I bring up Betemit, Chavez and Chad Tracy as LH options (switch hit in the case of Betemit) as viable options to back up Mauer and Plouffe, and even provide some platooning a 3B with Plouffe. We need that LH option to balance. And once again, whenever Sano is ready to take over, regardless if Plouffe is traded, or turned in to a poor man's Cuddyer, (not a bad thing) that LH reserve bat provides real value.
I won't get all grumpy if we add Reynolds as a bench bat, but I just think it is the wrong direction.
Couple issues I see, again I don't think Reynolds is some world beater, but he would come cheap, and if you needed him to play 10-15 games at 3B and another 5-10 at 1st base it wouldn't kill you that much IMO.
-Betemit is terrible defensively, extremely likely even worse than Reynolds. Betemit also hits pretty poorly. I don't see the real reason to bring him in at all personally.
-I like Chavez as a player, but he is 36 to enter next year, he is extremely injury prone and doesn't give you any real help against LHP. If Sano's timeline was 1 year out at this point, then I could see bringing him in, but I think he might cost to much to bring in for a couple months to potentially just be insurance for Plouffe (until Sano is up) Since he can't hit LHP he becomes a bit redudant at DH IMO. With that said, I wouldn't mind the Twins bringing him in, I just don't want to see them out bid the other 7 teams interested in him (per MLBTR) His defense has slipped as well. Frankly, I think Kubel has a much better chance to help out the team than him because of some of those reasons.
-I don't understand with the appeal of Tracy at all, other than a fluke 2012, his 4 other prior seasons (and 2013) were very ugly offensively. Defensively he isn't bad, but really isn't anything special and it hardly makes up. The upside frankly is not there. In the last 4 years he only had one where he didn't have a negative WAR.
Reynolds certainly has his warts, but he did have some solid somewhat recent success. I think he has significantly more potential upside then anyone else mentioned.
