$22 million/year is team friendly but not outrageously so. He's still more expensive over the next 3 years than Ryan or Ober will be. I doubt they keep all three, so I'd trade Pablo from that group.Pablo is on a very team friendly contract. Guys like Berrios and Musgrove are making more than him. I like keeping the staff in place. Buxton's is even more team friendly.
Correa definitely though. And the bullpen minus Duran and Jax. The rebuild has to be with the front office, coaching staff, owner and overall philosophy IMO.
I'd keep Jax and trade Duran. Buxton won't bring much anyway and is about your only marketable player at times, so I'd keep him.
Trading Correa will be complicated. Only a few teams would take the contract and he has to waive a no trade clause. Probably better done in the off-season.
