7. “Jazz Man”
This is what Utah’s announcers, and presumably Utah fans, call members of the team — and even ex-members. As in: “Paul Millsap, a former Jazz man, is having a big game against his old team!” I like it! It has a pleasing pop culture referent, and it’s a nice way of making up for the fact that a human player can’t be “a Jazz” in the way he could be “a Celtic” or “a Knick.” I’ve seen the Magic toss around “Magic Man” like this, and that hasn’t tickled me in the same way. What are the Thunder supposed to do?
