The 94th annual W-I-A-A state boys swimming and diving championships will be held at the University of Wisconsin Natatorium Friday and Saturday.  Monona Grove is a heavy favorite in Division Two, which starts Friday afternoon.  Monona Grove is going for a fourth straight title.  Madison Edgewood and Ashwaubenon are thought to be the best of the rest of the field.  Division One starts Saturday morning, with Madison West given a slight edge over defending champion Waukesha Catholic-Catholic Memorial.  Middleton and Madison Memorial could make some noise.
