We show that under rather general assumptions, the ratio of the masses of the 2/sup ++/ tensor and the 0/sup ++/ scalar glueballs in lattice gauge theory can be directly expressed in terms of two ground-state correlation coefficients. A simple variational estimate of these two coefficients in the case of SU(3) and SU(6) suggests that although these two masses remian highly degenerate in the intermediate-coupling regime, the ratio M(2/sup ++/)/M(0/sup ++/) never drops below 1 for coupling up to 1/Ng/sup 2/approx. =0.4, which is well beyond the expected scaling region.
