I'd take that trade, too, but it certainly is not a given, and that wasn't my point, anyway.
I was talking about the Yankee team from 2018-2020, who you added and who you lost.
The young players coming up should certainly help you, and likely more than the amount you lost with Paxton,Happ and Ottavino- certainly if just looking at 2020.
Losing Tanaka is huge, and you know it.
Kluber and/or Taillon could easily make up for his loss, but maybe not.
Sevy's return could be a big plus, or he could need more time to get back to norm of have a setback.
I'm not saying your outlook is not very good. I project you win the division, but it is not a lock. You do seem yo have more depth than recent years, but almost all of it is speculative to highly speculative, and when it comes to speculation, you always seem very rosy with Yankee players and very pessimistic with similar situated Sox players.
