Wow, lets trade futures for the great pending UFA Gaustad...
Leafs aren't a contender, and adding Gaustad isn't going to change that. I don't at all see the point of this proposal. The Leafs can just signed some of that calibre, or Gaustad himself, July 1st without giving up anything.
If you're not a contending team, then trading for rental UFAs is a really bad idea. Trading for signed guys is another thing, or pending RFAs.
Why trade a potential top 6 for someone best suited as a 4th line C? Gaustad is David Steckel with some grit.. I wouldn't mind him instead of Steckel, but there's no need for both of them, and especially at the expense of Matt Frattin.
