REDSKINS SIFTING: The Washington Redskins "are looking at" about 25 Plan B free agents, but don't expect to sign anyone until March, General Manager Charley Casserly says.

"We won't make any deals for a month," Casserly said. "We're looking at films. We're making contacts . . . We're talking to a lot of guys, nothing more than that," for now.

Players left unprotected under Plan B have two months to negotiate a contract with another team. On April 1, if they have not, they revert to their original club.

While the Redskins won't say it, word from the west is that they are one of a half-dozen clubs interested in S Ronnie Lott, a key to the San Francisco defense but exposed as a Plan B free agent. Lott has offered to take a $200,000 pay cut to continue with the 49ers. His attorney says though that the 49ers want an even deeper slice of the $1 million Lott is scheduled to receive for 1991. PRIORITY SHIFTING: Seven teams have changed positions in the first round of the 1991 draft as a result of the playoffs.

The first round of the 28-team draft, April 21-22, will include only 27 choices because the New York Jets used their pick in the July 1990 supplemental draft, when they selected WR Rob Moore.

The first-round position changes: Houston from 18th to 17th, Cincinnati from 17 to 18, Kansas City from 22 to 21, Chicago from 21 to 22, San Francisco from 27 to 25, Buffalo from 25 to 26, and the Giants from 26 to 27. BUGEL CALLS: Fritz Shurmur, Rams defensive coordinator the last nine seasons, has hired on in that capacity with Joe Bugel's Phoenix staff. Previous coordinator Joe Pascale, one of two assistants retained by Bugel from the staff of Gene Stallings, now will be placed in some other job with the Cardinals. ARRAIGNED: Browns LB Marcus Cotton entered a plea of innocent in Cleveland to charges of rape and sexual battery for which he was indicted Jan. 29. A bond was set at $5,000 and was posted, and the case was assigned for trial.
