One of the fun things about sports broadcasting is that it's a subjective business. You love Charles Barkley. You dislike Dick Vitale. Or vice versa. As part of SI.com's 2012 Media Awards, we want you to vote for the best and worst announcers of the year. We've already trimmed the field to six finalists for each category (yes, we know you might disagree with our selections). Make your picks by Wednesday at 9 a.m. ET and be sure to check back later on Wednesday when Richard Deitsch reveals the winners in his column.
