  The baryon- coupling to its current ($\lambda_{B}$), in conventional QCD sum
rule calculations (QCDSR), is shown to scale as the cubic power of the baryon
mass, $M_B$. Some theoretical justification for it comes from a simple
light-cone model and also general scaling arguments for QCD. But more
importantly, taken as a phenomenological ansatz for the present, this may find
very good use in current explorations of possible applications of QCDSR to
baryon physics both at temperature $T = 0$, $T \ne 0$ and/or density $\rho =
0$, $\rho \ne 0$.
