Assistant Coaches Bob Wenzel of South Carolina, Marty Fletcher of North Carolina State and Gerry Gimelstob of Indiana will be interviewed this week by George Washiangton University for the vacancy created when Bob Tallent was fired as basketball coach two weeks ago, it was learned last night.

About a half-dozen applicants will be screened by a three-man selection committee headed by Athletic Director Bob Faris, who will then make a recommendation to Lloyd H. Elliott, university president. GW would like to name its coach by the end of the week, sources said.

Others believed under consideration are John Kochan, an assistant at Maryland; Joe Boylan, an assistant at Rutgers who formerly was an assistant at both Catholic and American, and Joe Dean Davidson, the head coach at Dunbar High School.

The committee includes Edward Caress, GW's faculty representative to the NCAA, and Randall Packer, a biology professor who chairs the faculty senate's athletic committee.

Strong emphasis in picking the new coach is expected to be placed on his familiarity with the Washington area. Wenzel, who previously coached at Duke, has recruited this area extensively and is from New York, another GW recruiting area. Fletcher is a former De Matha player and assistant coach who recruited a number of N.C. State's Washington-area players. Gimelstob is from the New Jersey area and has been in two strong college programs, Utah and Indiana.
