Navy's Napoleon McCallum, earning most valuable player laurels, and Washington State quarterback Mark Rypien, a last-minute invitee after injuries created a vacancy, led the North to a 31-17 Senior Bowl victory today over the South.

Rypien, who joined the North team of college all-stars Tuesday and entered the game in the first quarter after starter Mike Norseth of Kansas was injured, threw an 11-yard touchdown pass to running back McCallum for a 7-0 lead late in the first quarter.

The North never relinquished the upper hand, and Rypien made it 28-10 with touchdown passes of 36 and 40 yards to Rennie Benn of Lehigh and Reggie Bynum of Oregon State in less than a minute early in the final quarter.

McCallum, carrying just eight times, gained 91 yards and decisively outrushed Bo Jackson, Auburn's Heisman Trophy winner, who led the South with 48 yards on 11 rushes. McCallum caught three passes for 31 yards; Jackson turned a short pass into a 48-yard gain to set up a third-quarter touchdown.

Virginia's Barry Word ran 20 yards on eight tries and caught four passes for 28 yards for the winners.

Norseth, originally assigned to the South but moving over when Robbie Bosco of Brigham Young and Jack Trudeau of Illinois had to withdraw, was hit in the mouth with five minutes to go in the first quarter and required 40 stitches.

The 6-foot-4, 225-pound Rypien completed 13 of 17 for 168 yards.

Auburn's Pat Washington and LSU's Jeff Wickersham each threw a touchdown pass to Louisville's Ernest Givens for the South.

McCallum earned an automobile as MVP in this game marking the participants' professional debut -- $2,250 going to each member of the winning team, coached by Dan Reeves and his Denver Broncos staff, and $2,000 to the losers, coached by Leeman Bennett and his Tampa Bay Buccaneers assistants.

Western Michigan linebacker John Offerdahl (North) was named outstanding defensive player.

"We'll sell the car," McCallum yelled to his teammates as he walked into the locker room, "and we'll throw a party!"

"It didn't make any difference to me what Bo (Jackson) did," said McCallum. "I wanted to play well myself and I did. It was a tough week . . . The pro coaches work you. But it was a good experience, one I would like to repeat."

McCallum is obligated to a five-year stint with the U.S. Navy.

"Napoleon does everything well," said Reeves. "If he stays in shape and works at it, I think he could be another Roger Staubach. He says he is going to save his 30-day leave every year and spend it in training camp with whichever team has his draft rights. That shows the dedication he has to the game."
