Chris Pronger came to St. Louis as part of a trade that divided the fanbase, and left the Blues as part of a trade that united the fanbase in its atrociousness.
Sure the Blues eventually got Jordan Binnington as a byproduct of the trade that sent Pronger to the Edmonton Oilers, but it was a blow to the franchise and the team’s reputation that took years to recover from - just ask Eric Brewer. Fans haven’t exactly forgiven former owner Bill Laurie for the deal, but over the years, Pronger has been a celebrated alumni of the team.
