All of Dallas' forward prospects are the exact same: right shot centers. They have no premium left shot wingers in the system. As I mentioned earlier - I see red flags when I watch him play but as you mentioned, as another poster before you: you do not see red flags in his play. I am proposing the Leafs should move him at what is probably his peak value for a prospect who is very similar but 2 years behind. It allows the Leafs to restart while allowing the Stars to pick up a position of need in their prospect pipeline in exchange for a position of strength.
And yes, his brother is on the team.
Edit: the same deal can be made for any of Dellandrea, Bourque or Johnston. I would think Johnston is untouchable though.
