since we're playing, according to cots, these players will still be under team control (not counting guys in the minors):
Werth
Span (last year of team control)
Harper
Zimmerman
Desmond (last year of team control)
Rendon
1st
Ramos
McClouth
Frandsen (last year of team control)
Gio
Zimmermann (last year of team control)
Fister (last year of team control)
Strasburg
Roark
Thorton (last year of team control)
Storen
Detwiler (last year of team control)
Clippard (last year of team control)
Blevins (last year of team control)
trades will obviously be made, but the only glaring openings are center field and first/second (depending on where you put Zimmerman/Rendon)
edit because of JCA's comment
cots right now has $87.4MM in firm commitments for 2015 before considering arbitration awards. This includes a $2MM buyout for ALR and only $500K buyout of Span's option if we don't exercise it. Assuming exercising Span's option adds $8.5MM additional commitments, bringing the likely non-arb spending up to ~$96MM.
I'm going to make some guesses at 2015 arb awards using the 40/60/80% of FA cost conjecture that FG uses, with some adjustments for leverage (will the team cut him?) and for players who have increased or decreased their FA value this year. SWAGs, of course, but it'll be something to give you an idea of the budget before extensions.
Fister is arb 3 coming off a $7.2MM year. Low end, figure he gets $10MM after a very good year. If you peg him as a free agent, $18MM AAV, then you could see him at $14MM. JZ will be getting $16MM this year.
Clippard is arb 4 off of a $5.875MM 2014. 25% raise would have him at $7MM+, which is steep for a set up guy.
Strasburg arb 2 off of a $3.975MM 2014. Figure no lower than what Fister got in 2014 as an arb 2. $7.2MM. I don't think he doubles to $8MM.
Drew arb 3 off of a $3.450MM 2014 (but is eligible for a 4th year in 2015). This values him at about $7MM as an FA, so figure $4.9MM to $5.875MM (Clip's 2014 number as an arb 3 with 4 years eligibility for arb).
Det arb 3, $3MM 2014. If he's back, then figure a slight increase to $3.2MM. His value is down because he is no longer a starter or a high leverage reliever. Looks like a candidate for possible release.
Rendon has an unspecified club option coming off of $1.2MM for 2014. Assuming it is equal to 2014, that's another $1.2MM.
Ramos arb 2, $2.095MM 2014. This seems very low, probably due to injury. I would guess he's due to double to $4MM.
Stammen, Lobaton, Frandsen are coming off ~$1MM contracts and arb eligible. Give them all slight bumps and say $5MM for the bunch. Espinosa is 1st time arb eligible, so figure $1MM.
I have not totaled this.
