Tuffers: an update

I didn't know what to make of former Latin American dance champion Shirley Ballas's comments on Tuesdays' edition of Strictly Come Dancing - It Takes Two. She described Tuffers as being a 'hard worker' with 'some rhythm' (with the emphasis very definitely on the 'some'). She went on to say that 'he'll have to work hard on his body movements.' Are these statements genuinely positive, or entirely euphemistic? Two days more, and all will be revealed.
