I wonder, with cap-space no longer being a problem, and with the Blues in need of some forward help in the top-6/top-9, if Jakob Vrana would be somebody the Blues would look at as a cheap (acquisition cost-wise) stop-gap. He recently passed through waivers and only has one more year at $5.25M.
Yzerman and Army are buddies and no doubt Detroit has gotten the better of those previous dealings. You'd have to think after having waved the guy and risked losing him for nothing that Yzerman would be happy to recoup even a mid-round draft pick for Vrana, along with some welcomed cap flexibility. And with the Blues collecting high draft picks in the coming years, they can afford to part with some later ones. No need to draft 10-11 guys unless you have places for them to play.
