Blues had a major part in that. In some of the earlier years of the affilation, Rattie, Jaskin, and Allen were big contributors. In the last year when they got to the 2nd round with Berube, the Blues provided all the goalies, Dunn, Blais, Barbashev, Paajarvi, etc. In all the years, the Blues provided plenty of AHL vets that were major contributors as well, guys like Butler, Agostino, Megan, etc.
The issue with Chicago just came down to the balance between prospect development and short-term performance.
