How I see it:
Locks: 2B Steer, SS Palacios, 2B Julien, OF Wallner, SP Canterino, SP Woods-Richardson, SP Varland
Borderline: RP Schulfer, C Isola, RP Mooney, RP Headrick, RP Gipson-Long
I would definitely protect Isola and I'd consider the others, but that's 8+ prospects. I'd be fine moving on from a couple - I'd prefer to keep the starting pitcher prospects, and I'd be willing to move Steer (sell high) / Julien / Wallner.
