Well you either sell high or as I would suggest see what you have and if not sell at the deadline. Still value in those guys and you could get some very nice pieces back at the deadline if you aren't there. Thing is to cut your losses at the deadline if you are 4 or 5 games out.
As for money , Morrow, Rasmus, Happ, Santos ,and possibly Melky and Jansen will all be gone . Bull pen will require a closer if Casey leaves and if Melky leaves you will need an OF unless you go with Reimold in left and Gose/Pillar in center. Plenty of money since not many free agents will play here.
