Well, after quickly looking a to top picks in every draft since 1988 I think the answer is Danny Manning in that year. Larry Johnson was the top picks the year after UNLV won the championship. Mike Bibby went to No. 2 (that sounds funny) the year after U of A won the championship in 1997. Jason Williams was the top college player taken a year after Duke won the championship.
I think Danny Manning's the answer to your question.
