I think these Winter Meetings will be among active as we've seen in awhile. I'm not all that certain of what the Cubs might do but previously predicted that they would trade for Archer and my gut still tells me they will. Some predictions and thoughts:
All 3 prominent FA closers sign this week starting with Melancon to the Giants as early as tonight. I think Chapman ends up a National and Jansen remains a Dodger, but I think LA sheds some salary first or he winds up elsewhere. Wild guess would be the Marlins but I was sort of surprised they were in so hard on Melancon so this is by no means more than a strange hunch.
The Cubs make a deal with Tampa Bay bringing back Archer and Colome but if the price is too high for Archer I think the get Colome anyway. He fits the Cubs MO as a 27 year old arm with 5 years of control and his numbers are impressive especially K's. Whether it's Archer and Colome or just Colome I don't expect Baez to move. I'd be very surprised but not absolutely shocked if Russell goes in the deal for Archer plus, I think the FO thinks Baez' ceiling is higher and if they have to part with one it would be Russell.
If Archer comes north I think Arrieta is moved. Houston is as all in as anybody and could use another pitcher and it's looking like they're out on Sale who would cost Bregman plus. I think there would have to be a sweetener along for the ride but I think this could bring back an arm. David Paulino wouldn't shock me.
Sale stays put, Quintana stays put, Archer goes if it's the Cubs or maybe Boston if they trade in Division. Unlikely but there is a fit. Atlanta is a player but won't part with Dansby Swanson. Hill signs in LA (if he hasn't already), Boston trades for Verlander, the Yankees sign Jason Hammel.
Encarcion lands in Houston, Bautista in NY, Fowler to Toronto, Ian Desmond back to Washington if they can't land McCutchen. If the latter isn't a National I think he's a Ranger.
I think the Mets, Braves, Astros, Nats and Cards are the most active of the contenders but the Cubs, Giants, Dodgers, Red Sox and Rangers all potentially have a big move in them. Of the rebuilders I think the D-Backs, A's and White Sox will be active but I don't think the latter moves pitching unless it's Robertson. Frazier and Abraeu might net the most back otherwise unless they move Eaton.
This was all stream of consciousness stuff and is probably mostly wrong but hell why not make some guesses?
