ROSE BOWL FEVER: Christmas Day will bring the Rose Bowl-bound University of Michigan Wolverines' football team to Orange County. . . . The entire 293-room Waterfront Hilton at Huntington Beach will be taken over by players and families, coaches and staff. The team will practice at Orange Coast College. . . . Why the Waterfront? "The players want to experience California, and where better to do it than at the beach," says the hotel's Phil Johnson.
