Of the entire Blues cup winning roster, Chicago Wolves alumni were a minority of the roster. Only a handful of players like Binnington, Dunn, and Barbashyov spent a respectable amount of time in Rosemont. Parayko (half a season after finishing college) and most of the claimed alumni ever played less than a full season total for the Wolves. Most of the big names on the cup winning roster were free agent and trade acquisitions, and most of the younger players spent much more time in San Antonio than Chicago. Not nearly enough to repair the damage with most of the comments and potshots that were called a few years ago. It was a bad marriage that ended badly.
But unless St. Louis manages to find an owner willing to sell their AHL franchise, which Vegas showed is incredibly unlikely, they won't have much of a choice. They'll both need to swallow their pride.
