Of course Leaf fans would like to see revenge. But this is a completely different team since 2013 and our team's foundation is just beginning.
I think having Bozak/Komarov for the playoffs and then letting them walk is more valuable than trading them for nothing and dismantling the team's chemistry. Also, I don't think we can replace Bozak's centre position or Komarov's defensive skillset/pk ability/leadership, etc.
JVR I would be less hesitant to trade, but his production is not easily replaced. But if he nets us a solid 4th line centre, RHD, picks, prospects, or whatever is needed, I'm game.
