A few days before that trade, Boston played the Caps at Landover, MD, and I was at the game. Anson Carter scored 2 for the Caps, and the rumors were that Mike O'Connell was very impressed with Carter from that game. And you are correct, Wally, that da Broons were given their choice of any of the 3 Caps' goalies--those 2 plus Dafoe.
BTW, the Caps had one of the best prospect pools in the league at the time, and it was stated that other teams mocked da Broons for getting Allison and Carter, and not one of the Caps' young star prospects. However, I think da Broons had the last laugh, as both Allison and Carter became high-quality NHLers. One person, I remember stated that Allison was so good that he dominated half of da Broons' games in which he played. He was a lot like Coyle, but with much better hands and stickhandling ability. In other words, not a fast skater, but once he got the puck on his stick in the offensive zone, nobody took it from him. Like Coyle, a possession monster.
I don't know if people remember, but Konowalchuk was supposed to come to da Broons as well, but when Poile found out that Tocchet was about to become a UFA at season's end, he was pulled from the trade, and subbed with a conditional 2nd, if Tocchet re-signed with Caps, which he did not. Wow, quite the sentence! LOL.
