Late in the 1990–91 season, the St. Louis Blues were in first place overall and GM Ron Caron was looking to improve the team's defence for the playoffs. On March 5, 1991, at the trade deadline, Caron traded four players and 1992 fifth-round pick (Brian Loney) to Vancouver for Butcher and Dan Quinn, a small but skilled centre. Butcher was the key player for the Blues, with Quinn added due to the Canucks hard negotiating. The Blues traded away Geoff Courtnall, Robert Dirk, Sergio Momesso, Cliff Ronning – who as a group invigorated the Canucks for a number of years and eventually helped their new team advance to the 1994 Stanley Cup Final.
The Butcher trade helped the Canucks but cost Butcher's new team dearly. Traded away such depth cost the Blues a second scoring line behind Brett Hull and Adam Oates. As a result, the trade was blamed for the Blues defeat at the hands of the Minnesota North Stars in the second round of the playoffs. (The Stars would make it all the way to the Finals). Quinn was gone from the team shortly after the playoff disappointment. The Butcher trade (together with a later lopsided deal favoring the Canucks) was regarded by media and fans as one of the top 5 heartbreakers for the St. Louis Blues.[10]
Butcher was expected to provide leadership. He was named team captain, but a broken left foot cost him the end of the 1991–92 NHL season and the start of the playoffs. After the Blues were eliminated, Butcher was selected to the national team for the 1992 Ice Hockey World Championships. He played three games and scored a goal. The team placed eighth.
Butcher played in the NHL All-Star Game in 1993, but as an injury replacement for Jeff Brown. The same year, Butcher scored a rare goal, the game-winner, against the Toronto Maple Leafs in Game 3 of the 1993 Norris Division Finals.[11]
