The risk is overpaying to keep the status quo, which clearly isn't working, intact. Overpaying for Dozier (my guess as to which one would get it if only one were to) would give "well, we paid Brian, now we need the young guys to step up more" excuse to fall back on. Enough "bad signings" (Morrison, Lynn, the hypothetical overpaying of Dozier/Escobar) and the purse strings will tighten back up if there's no on-field results.
