So interesting to hear people's views on name-dropping. I did last year, and, granted the rest of my application was rather weak, I didn't get in anywhere. This time around, I decided I would go for the no-name approach. It worked out alright. I think it's important to convey fit throughout your SoP so that the folks you could work with would be obvious to the admissions committee, even if you don't spell it out. But that's just my take..
