Tom Young, Rutgers basketball coach, has emerged as the leading candidate to replace Norman Sloan as coach at North Carolina State, according to sources at State.

Young, former coach at American and once an assistant at Maryland, was in Raleigh yesterday to be interviewed. He has coached at Rutgers for seven years, leading the Scarlet Knights into the NCAA final four in 1976. This season, Rutgers had a 14-14 record with three freshmen starters.

Others reportedly still under consideration by State include Jack Hartman, Kansas State coach; Charlie Moir of Virginia Tech, and Jim Valvano of Iona. Morgan Wootten, coach of De Matha High School, has turned down the job.

State is not expected to name Sloan's successor for at least another week.

Such is not the case at Duke where Athletic Director Tom Butters is expected to announce his choice as Bill Foster's replacement no later than Thursday.

Reportedly, that field has been narrowed to two: Foster's top assistant, Bob Wenzel, 30, the choice of the players and many of the alumni, and Mississippi's Bob Weltlich, 34, named Southeastern Conference coach of the year after a 17-13 season.

Weltlich has withdrawn from consideration for the vacancy at Iowa State. Wenzel has said that if he is not Duke's new head coach he will join Foster at South Carolina.

Wenzel, six years an ACC assistant under Foster, also played a major role in Duke's recruiting of players such as Jim Spanarkel, Mike Gminski, Eugene Banks and Kenny Dennard. Those players are largely responsible for Duke winning two ACC championships in the last three seasons.

Boston College Coach Tom Davis and Old Dominion Coach Paul Webb have been interviewed by Duke officials, but neither is being considered at this moment, according to informed sources at the school.

In one other coaching development yesterday, it was learned that Marty Fletcher, State assistant who coached under Wootten at De Matha, is a candidate for the Navy job. Bob Hamilton was fired last week.
