Agree he would be a great add. Stick him in the #2 slot and play DH/utility. He played 1B last year.I would give my left testicle to see Arraez in a cubs uniform. I just have no idea where you play him. Personally would move Nico to short, play him at second, and bench Swanson, but that isn't going to happen. Just have a hard time seeing this cubs mgmt having a guy with little power in the DH spot. But man that dude can hit, he's exactly what we need in the lineup.
If Nico got hot, could go Arraez, Horner, PCA, Bregman, Suzuki, Busch. That's a really solid top 6.
Arraez doesn't have much power, but Swanson has good power at short and the entire OF could hit 30 HR's.
