I agree that it's too big of a jump.
A deal between the Nucks and Leafs just makes too much sense to me.
Vancouver has Horvat and the 6th this year as top young assets but they can't wait on them because the Sedins, Bieksa, Hamhuis, etc. don't have enough time left. Vancouver desperately needs some 2nd line which Lupul or Kadri would instantly give them and they can live with either of their defensive shortcoming.
Toronto can afford to take a step back and deal some current players for top quality youth like Horvat or 6th overall as the main piece.
