BOSTON — The Florida Panthers acquired Brady Tkachuk. The Toronto Maple Leafs traded for Darren Raddysh and are reportedly pursuing Vincent Trocheck. The Ottawa Senators and Buffalo Sabres are eager to use the futures capital they imported for Tkachuk and Bowen Byram. Don Sweeney is feeling a little left out after watching his Atlantic Division competitors.“I don’t think the transactions are going to stop between now and the timeframe in July. We’re eager to be participating,” the Boston Bruins general manager said on Wednesday at Warrior Ice Arena. “Haven’t yet.”In his conversations with other GMs, Sweeney is asking about right-shot defensemen and top-six skill. They are commodities he could target come July 1 as well. But Sweeney is not interested in standing pat until the opening of free agency.“You have to be in the trade market at this time of the year,” Sweeney said. “I just don’t think you can be singularly focused on UFA, internal growth and the expectation that someone’s just going to take the job. You’ve got to go out and actively find some guys that your pro guys have identified that can help.”Brady Tkachuk to the Florida PanthersSean McIndoe and Sean GentilleThe Bruins are short on right-side contributors behind Charlie McAvoy. The No. 1 defenseman is ineligible for the first six games of 2026-27 because of his Game 6 slash on Zach Benson.At forward, the Bruins took a good step last year in the muscle department by signing Tanner Jeannot and watching Mark Kastelic reach another tier. Their priority is to incorporate more speed and skill to increase the offensive metabolism.“Getting better in the forecheck side of things,” Sweeney said of the organizational wish list, “and creating a little more anxiety.”
