I really do not think Thomas was all that. His jab was good but it was vastly overrated it wasn't close to a Holmes jab.
Thomas easy UD. Both have great chins and neither is hurt but Thomas jabs Bonecrusher all night long and lands some nice right hands. Bonecrusher kod Bruno who gassed and didn't have the best chin. Thomas was at his peak in '84.
I do think that Smith would be able to potentially hurt Thomas (Weaver was able to do as much) but yeah, no hope of winning for him here. Thomas win either on a clean decision or cuts, just like Holmes.
