I really liked Cawood Ledford too. My favorite line that he used to say was, "Terrible call!" or even better, "ATROCIOUS CALL!!"
Jack Buck is one of my all time favs too.
My favorite hoops man (color) is Bill Raftery. I still remember watching a Pitt game in I think 1988 he called. Jerome Lane did a monster dunk and brought down the backboard, then he said, "SEND IT IN, JEROME!" I still love that call, probably my favorite of all time.
I know most people hate him, but I like Dickie V.
My vote for worst goes to these hoops announcers. Billy Packer (most overrated, terrible announcer of all time), George Raveling, Bill Walton, and the immortal, JOE DEAN.
