ESPN has a tourney blog up that is just awful. Just two guys sitting aroung giving play by play with stupid jokes tossed in. It's not really adding much when you can get the play by play on all the major sports sites minus the jokes.
You can check out a much better college basketball blog on Sportsline.com, Doyel's Dribbles.
Update: As soon as I recommend Doyels blog he stops updating. I guees he is too busy writing regular columns for sportsline.com. I hope he resumes the blog when the tourney is over. He has strong opinions but doesn;t take himself too seriously. Good qualities in a blogger.
