Theme: Names that begin with two initials. The two letters are alphabetically in reverse order.
6A. Box with handles? = C.B. Radios
17A. “The Invisible Man” author = H.G. Wells
22A. Washington M.L.S. team = D.C. United
35A. “The A-Team” character played by Mr. T = B.A. Baracus
49A. Educational institution near Plano, informally = U.T. Dallas
60A. Some return addresses = P.O. Boxes
64A. “Four Quartets” poet = T.S. Eliot
This seemed way too easy for a Thursday puzzle (I had more trouble with Wednesday’s), and I completed it in under an hour. I quickly figured out the initials theme, but the reverse alphabetical component escaped me. Found that out when I checked Rex Parker.
