I don't think you'll see the Leafs give up their 1st round pick next year, even with a condition.
For a 22 year old RHD who would likely be signed 6-8 yrs and projects to be a top pairing D. I make that trade. Yes it would suck loosing out on potentially a player like Foote but who knows where we pick. Its top 5 protected so if we are a lottery team and get top 5 pick we get our man.
We have a ton of LHD that should be ready to make the jump, and some that will up with the team maybe next year (Dermott).
