Yeah, but look at the actual list (which you obviously have). Of the 10 pitchers on it three are gone (Eickhoff, Rios, Anderson). One is Arano (who is obviously a concern but not a fungible). Suarez is promising and still just the third-string lefty. I'm not sure Davis is still on the 40 come spring. Irvin probably goes back to starting in AAA. And whatever they are doing with him De Los Santos isn't being counted on either. That just leaves Garcia and Hammer who are still towards the bottom of the pen (certainly Hammer won't be starting in the big leagues).
As much as I would like to see one theoretically more reliable arm, those 250 innings (plus the ones we got form the July waiver guys) were still the product of an epic bout of injuries. Unless and until the bodies start dropping again they won't pitch, there isn't actually that much roster space, and what's available to the Phillies at this point won't necessarily be clear upgrades.
Pivetta (or Velasquez)
That probably leaves one spot for Stock or Kelly and one spot for guys with options. And I do think there will still be others in the mix (from minor league deals or waiver claims).
I think it comes down to Velasquez or Pivetta at this point. If you're not sure the guy who doesn't win the starting job can at least be a solid 7th inning reliever you should trade him. Either straight-up for a reliever or for a couple of lottery tickets that alllow you to do a separate deal (while also freeing up $3-4 million) for a reliever.
