NFL coaching on the coordinator level grows more and more like baseball managers' musical chairs: Rod Rust, director of Kansas City's defensive unit the past five years, will coordinate the New England defense . . . Upwardly mobile, though, is Dick Wood: from Atlanta quarterback coach to Philadelphia offensive coordinator. Five years helping Steve Bartkowski develop, now Ron Jaworski? Yes, Wood assures, Jaworski will be his quarterback . . .

Yet another beefing Bill. All-pro defensive lineman Fred Smerlas quoted after the Pro Bowl as ready to ask Coach Kay Stephenson to trade him: "I don't want to waste my career with a loser and I don't see how Kay can win in Buffalo because his hands will be tied by management" . . .

Amid scads of USFL no-name cuts, Philadelphia's Stars schedule a big-name signing announcement today, likely No. 1 draftee Irv Eatman, UCLA lineman, and Kelvin Bryant, North Carolina tailback . . .

Joe Blair is out and Charlie Taylor (not Charley the receivers coach but Charles M., the pride of Fairmont, W.Va.) is in as Redskins' public relations director. Taylor, 33, has been the assistant director since 1976 and the promotion comes as he and wife Lynn await their first-born, due in June. Blair leaves his second stretch with the Redskins (1963-74, 1978-now), to "pursue several business opportunities." Both club and Blair seem to feel the move is for the best . . .

Last call, Quarterback Club tribute to Joe Bugel and his Redskins offensive line Hogs, 6:30 tonight, Touchdown Club (call there for reservations).
