George Mason University will name its basketball coach today at 11:30 a.m., presumably from among four finalists identified yesterday by Athletic Director Bob Epskamp.

Vince Campanella, sports information director for the Fairfax school announcing the scheduled news conference, allowed, however, "I think everybody will be a little surprised." He would reveal no more.

The four possibilities named by Epskamp included Joe Harrington, former player and assistant coach at Maryland; Joe Dean Davidson of Dunbar (D.C.) High; Jim Lewis, assistant coach at Tulane who formerly starred at Groveton High, and Ed Hall, associate coach at Wake Forest.

At his request, Harrington was the only candidate among seven interviewed by Mason's search committee who was not identified publicly last week. In fact, two weeks ago, Harrington, head coach for the past year at Hofstra, said he planned to remain there.

When John Linn resigned last month at GMU, after 10 years as a part-time head coach, and the Patriots decided to hire their first full-time coach in any sport, Harrington's name was prominently mentioned.

Besides the four finalists, other coaches interviewed by GMU were Jack Kvancz, head coach at Catholic U.; Ed Green, head coach at Roanoke College, and Allen Van Winkle, head coach at Jackson (Mich.) Community College.

Meanwhile, Navy which fired Bob Hamilton last month, is expected to name its new coach later this week, Athletic Director Bo Coppedge said.
