The blues do this trade to add a high quality RW. This will help shore up that position by adding another high quality guy to pair with Tarasenko. Matheson started out slow this year but has started to pick it up as of late. Kunin and Beauvillier are a couple of young wing prospects that have both had some NHL time and are close to full time roles.
