If Okamoto is 3yr, $45M or less, it would be worth it for the Cubs. Supposedly, he can do 3B, 1B and outfield. I don't know how good he is as a defensive dude, but he could be our utility guy who can hit better than most utility guys, and he can do DH, if he can actually hit well. He got three gold gloves in Japan, but Seiya got more (maybe, 5 times?). So, I really don't know his defense. Okamoto fits way better than Murakami for the Cubs.
Then, forget about Bregman, which doesn't make sense to me, unless they really want to trade Nico, or don't like Shaw. Then, they should have enough money to sign Imai or whoever like Valdez or Suarez.
