You don't need The Tennis Channel to watch Wimbledon 2007, which is good news if you don't get The Tennis Channel. If you do, though, the fact that ESPN2 is in charge this year means, for now at least, that John McEnroe isn't announcing, which is a major bummer. Tennis announcing on any network has in the past usually involved some combination of the same cast of characters: Mary Carrillo, the two McEnroe boys, Cliff Drysdale, Mary Jo Fernandez, Martina Navratilova, Pam Shriver, Luke Jensen. The major networks always supply a play-by-play commentator to accompany a couple of the above-mentioned tennis greats, who actually know how to talk about tennis. In the old days on the final weekends it was Barry McKay or Dick Enberg maintaining the hushed informational chatter, and then you had to put up with Bud Collins squealing and rhyming at intervals. But something strange is happening to tennis right now. ESPNization, having claimed all other sports, has come to the ladies and gentlemen of the tennis world. And Chris Fowler, of College Game Day, is our guide to Wimbledon 2007.
