There are so many Roman baths, so unless it's your specialist area it can be very difficult to get worked up about another one. This one seems to be interesting for a variety of reasons. The excavators seem to be linking it to the Roman soldiers that destroyed the city following the Bar Kokhba uprising. A dog footprint was found, presumably from a working dog that belonged to one of the soldiers rather than a pet, impressed into one of the roof tiles along with the symbol of the Legion (their photo above). And it was found under a later Miqve, showing continuity of use for bathing - a Miqve is a bathhouse used by Jews for ritual purification.
