Kicker Mark Moseley, defensive end Coy Bacon and guard Jeff Williams have signed new contracts with the Washington Redskins.

Moseley, who led the National Football Conference in points last season, agreed to a series of five one-year contracts that probably will make him one of the league's highest-paid kickers.

Williams, who started all of last season for the injured Dan Nugent, signed a series of four one-year contracts.

Bacon, who led the club in sacks last season with 15, agreed to a one-year contract. He will be 37 at the start of the 1980 season.

With those signings, the Redskins have reached the one-third mark with those athletes who will be in the option years of their contracts next season.

Among the key players unsigned are tackle George Starke, safety Mark Murphy, defensive end Karl Lorch, end John McDaniel, linebacker Pete Wysocki and Nugent.

General Manager Bobby Beathard said he was still at an impasse over contract terms with halfback Benny Malone. He also said that the club and reserve middle linebacker Don Hover are far apart in negotiations.

Moseley is coming of his finest season. He made the Pro Bowl for the first time while leading the NFL in field goals (25). He was also the only kicker in the league to make all of his conversion attempts. He holds the majority of the Redskin kicking records.

Bacon began last season as a reserve but won back his end spot two games into the schedule. Besides finishing first in sacks, he also was tops among defensive linemen in tackles.

Williams is considered to be one of the best young linemen in the league by the Redskins. "He's been working hard in the offseason for the first time," Coach Jack Pardee said, "and I think he will be ready to have a great year this season."
