IMO as of today:
NL East -
Washington
then in any order and likely dependant on health and luck
Phillies
Mets
Braves
SP - Nats, Mets, Braves, Phillies
RP - Mets, Phillies, Braves, Nats
Lineup - Phillies, Nats, Braves, Mets
Bench - Nats, Braves, Phillies, Mets
Best overall Pitching - Mets, Nats, Phillies, Braves
Best overall hitting - Phillies, Nats, Braves, Mets
Keuchel, Kimbrel, Gonzalez, Maldonado, Madson, Warren, Sipp left to sign.
If the Braves added Keuchel they still wouldn't pass the Nats or Mets. I see the Phillies making a run.
If they signed Kimbrel they probably pass Philly but not the Mets in RP. Expect the Nats to make an offer IF he signs in the NL East.
Gonzalez would be filler and not move the needle at all for the Braves. Again Phillies maybe.
Maldonado might end in Philly.
Braves probably get one of Madson, Warren or Sipp.
Or they get nothing and the NL ends up with none of the leftovers.
Health and luck. That's what the Braves are praying for now.
