The Washington Capitals made two trades last night, acquiring Hartford forward Dave Tippett and Buffalo defenseman Shawn Anderson, while losing defenseman Bill Houlder.

Houlder, who played half of last season with the Capitals but wasn't likely to make the squad, goes to the Sabres for Anderson, who was in a similar position with Buffalo.

Tippett, 29, has been a regular for most of the past seven seasons with the Whalers. Hartford will get what Capitals General Manager David Poile called "future considerations."

Poile said he would say what the future considerations are on Tuesday. The timing involves today's waiver draft. It's possible the player going to Hartford will come from the list of players not protected by the Capitals.

The list of protected players had to be submitted to the NHL office last night and will be released this morning. The Capitals declined to release it last night.

Goaltenders with three years of pro experience and skaters with two years of experience are eligible for the draft. The Capitals now have 29 such players or the rights to such a player.

Each team can protect 18 skaters and two goaltenders. The Capitals will likely protect goalies Mike Liut and Don Beaupre; defensemen Rod Langway, Bob Rouse, Mike Lalor, Calle Johansson and Kevin Hatcher; forwards Tim Bergland, Dino Ciccarelli, John Druce, Dale Hunter, Nick Kypreos, Steve Leach, Alan May, Kelly Miller, Rob Murray, Michal Pivonka, Mike Ridley and Peter Zezel. Tippett is also likely to be protected.

Anderson, however, almost certainly will not be protected, so it is possible he could be taken by another team before he ever plays for the Capitals. The others likely to be left unprotected are forwards Jeff Greenlaw, Bob Joyce, Alfie Turcotte, and defenseman Chris Felix, Mark Ferner and Kent Paynter.

Defenseman Neil Sheehy, who is out for three or four months with a broken ankle, will not be protected, nor will Robin Bawa, who signed as a free agent with Fort Wayne of the International Hockey League, but whose rights belong to the Capitals.

Poile said Tippett has value as a penalty-killer.

"I've always really liked him as a player," Poile said of Tippett. "We tried to sign him when he was a free agent {in 1988}. He's a winner and one of the premier penalty-killers in the NHL. Look at Hartford's percentage killing penalties over the last few years."

Hartford had the fourth-best power play-killing percentage in the NHL last season.

Anderson, a No. 1 draft selection in 1985, spent the last four seasons splitting time between Buffalo and the team's Rochester farm club. Houlder played 41 games with the Capitals last season, finishing with one goal and 11 assists.

"With Houlder and Anderson, it's one of those situations where sometimes the grass is greener somewhere else," Poile said. "Their careers have gone somewhat parallel to each other. Both players wanted to either stay with their NHL club or be gone."
