Calvin Hill, who said he would retire and begin law school rather than sit on the Redskin bench another season, will return to the club, coach- general manager George Allen said yesterday.

"Calvin's going to be back and better than he was last year," Allen said during a minicamp at Red skin Park. "We want him and plan to give him more playing time."

Hill, a 227-pound tailback, signed as a free-agent last year and expected to be one of several backs rotated during the season. But when the year ended. Hill had carried only 79 times for 301 yards.

Hill, 30, an eight-year NFL veteran, did not attend the sessions at Redskin Park this week. Hill is reportedly visiting friends on the West Coast and could not be reached for comment.

Although guard Paul Laaveg, tackle Tim Stokes and linebacker Harold McLinton are all free agents. Allen said he expects all of them to be at the team's Carlisle, Pa. . training camp in July.

Linebacker Chris Hanburger, wide receiver Charley Taylor. Cornerback Pat Fischer and defensive end Ron McDole all took and passed physical exams, on Monday. Center Len Hauss was excused from the physical because he was taking law-school examinations in Georgia.

Forty-five players attended the opening of the three-day minicamp, but only 12-a group Allen calls "young veterans" - were on the Redskin roster a year ago.

The remainder were draft choices and former free agents, including linebacker Greg Hartle, who play out his option with the St.Louis Cardinals, and running back Willie Spencer, a World Football League star who played three games last season with the Minnesota Vikings.

Allen's No.1 priority going into training camp is to improve the defense, especially the pass rush. That's why the Redskins' first draftee was Duncan McColl, a 6-foot-4, 240-pound defensive end from Stanford.

Allen is seeking more quickness from tha front four and an injury-free season. Bumps and brusises, Allen said, hampered the pass rush effort a year ago and necessitated more blitzing by the linebackers.
