The St. Louis Blues have made plenty of big deals during their 50-plus years of existence. They might not have the longevity of other franchises, but they have not shied away from the occasional blockbuster deal.
Of course, deals that brought the franchise changing Brett Hull to town are near the top. There is also the late-February deal that brought Wayne Gretzky to the Gateway City, and also shows how much the trade deadline moves around.
However, there was one particular trade that happened on March 5, 1991. That trade was made with a plan to put the Blues over the top.
