That last list was focused on 2015. That's what I prefer because a lot can happen between now and later, a surprise guy develops and one guy isn't as needed. A prospect crashes and the only other prospect at that position becomes more critical. But as we stand here today (and because what if anything happened of consequence over the weekend?) here's the quick take on how I'd change things up thinking beyond 2015
#1 Rendon - long control, MVP potential
#2 Bryce - not quite as long control, question marks but way too talented and part of two-man offensive core
#3 Sherzer - the defacto ace they are working around for the next several years
#4 Zimmerman - He's paid a lot for a long time so it's better if he can play
#5 Giolito - you can't build around prospects BUT Top 10 guys... well it's hard to keep yourself from doing that and if the Nats let everyone walk in the next 2 years, he's the reason why.
#6 Roark - very cheap effective starter in hand for years if last year wasn't fluke
#7 Werth - Still three more years of big money and don't see corner OF replacement in minors
#8 Taylor - Next closest ready minor leaguer, allows for Span to walk which looks like it has to happen at this point
#9 Strasburg - Healthy Stras matters, as a rotation anchor in 2016 before leaving, a potential keeper if Giolito flames out, or trade bait.
#10 Gio - has potential to be underpaid starter through 2018. Of course mostly healthy last year didn't look great.
#10.5 RAMOS - dammit I knew I left someone out.
#11 Escobar - keeps team desperate from needing to resign Ian or form some other short term solution
#12 Storen - there are guys in line but it'd be best if Storen were healthy for roughly same reasons as Strasburg.
#12 Turner - keeps team from needing new long term Ian solution, though long term sometimes things just luck out for you.
#13 Barrett - They like him and he's under control for a long time.
#14 Lobaton - Could be a temporary starter if Ramos goes or goes down. Most likely a nice back-up for 3 more years.
#15 Difo - Could move up this list quickly with good showing in AA, a little too question-marky though to be higher. Makes list because Nats MI prospects are shallow.
There you go - discuss. 20 days now!
