That player that you're looking for doesn't come on the market for at least the next two years. Happ and Suzuki are the two best bats available in Free Agency this year and Kyle Tucker (if he opts out) and Teoscar Hernandez are the two best the year after.Cubs have to shake up the clubhouse. Plus, NLCS caliber teams need stud players in the 3-5 lineup spots. PCA is playing at that level, but he may be too valuable as lead-off guy. Otherwise, guys like Suzuki, Happ, Busch are 6/7 spot players in an NLCS caliber lineup.
Cubs are paying Suzuki & Happ $40M. I would rather pay a stud corner OF $30M and find a productive bat at $10-12M for the other corner spot. Heck, I'd be OK with Shaw in one of the corner spots if it allowed for signing an elite slugger.
***Acuna can technically be an FA after this year but there's no way he doesn't re-work his deal with Atlanta and stay.
