The Hull trade is a weird one. On one hand, yes it was very lopsided. A HOFer who would go on to score well over 700 goals for who I believe at the time was a 2nd pairing defenseman, and a backup goalie just looks insane. Neither stuck around for very long either, and obviously Hull was a franchise/franchise saving player for St.louis. Would Calgary still do that trade if they knew what Hull would become? Maybe, if they also know they would win that Cup, but they probably try to find another way to get it done.
On the other hand, it was one of those sacrifices that a team right on the verge of winning makes. Wamsley I wouldn't say "threw them over the top" as he was just a backup and I don't think really even played in the playoffs that year (maybe one game), but Ramage certainly helped. They won their Cup, and that's what it's all about, but in the end it was still an extremely lopsided trade.
Maybe they win it anyways, very possible, but I would say that the Gretzky trade to L.A. may have had just as big of an impact on the Flames' championship, some would argue much bigger. Regardless of how highly anyone wants to rate Ramage's impact, if they don't win that one Cup then this trade certainly skyrockets to near the top of any "Worst Trade" list. Their only saving grace and justification for trading a future superstar and one of the top few greatest goal scorers of all-time is, "They won a Cup."
Just a weird one that could be looked at from different angles.
