Phillies are already a 90+ win team (87 with Harper effectively MIA for 2/3 of the season).
At this point they should get their finances stable, keep building the organization, and stay out of top money free agency.
Let Hoskins play out the string, pick up Nola's option year but don't extend him (because you'll end up paying for his downslope seasons at a premium price).
You can only carry so many big contracts, and as this season showed, you need a strong organization b/c injuries and players falling off is inevitable.
In two years, if you clear a bunch of salary, you'll know which kids stepped up and where you need to spend.
But why not go into next season with this team and maybe add a little more pitching depth? A SP and a RP.
Start building depth at AA and AAA ball, and find out how good Painter, Abel, McGarry, Baker, Rojas, Marchan et al are, and whether Marsh, Veirling, Stott, Bohm, Maton, Sosa and Guthrie have any more upside.
