I can handle the concept here, but too many other assets coming back for a team "rebuilding". The draft picks are on the right track, but I think its too much return for Toews.
Moreover, I'm not sure they would be interested in a Toews type player. Kane would be a better fit.
In order to make the Kane trade happen, I'm thinking at least one first plus Wahlstrom and Dobson. Also, the hawks won't have interest in Bailey or Cal so I would suggest a 3 team trade where someone else is getting something from the Hawks to get those 3 prospects.
