No incentive for Ottawa. They don't need the cap space, and Ryan is still a useful player for Ottawa. They'd rather keep the pick

Bobby Ryan is good enough that Ottawa could still get a little something for him, though not much because of his contract. They won't have to pay someone to take out the trash.

The EDM trade is too complicated. Simplify it to Lucic, Puljujarvi and the EDM #1 (eighth overall) for MTL #1 (15th) and a conditional pick based on Puljujarvi's NHL performance over the next 2 years. Edmonton doesn't likely want Hudon (does anyone?) or Peca.

I'd simplify it further. Edmonton keeps their broken players and Montreal picks 15th.
The difference between 15th and 8th just doesn't justify taking Lucic, and there's no need for Pulj to be moved. Hudon will be a UFA and Peca would just be an expensive bottom 6er.

Montreal would really be taking a 1st for Lucic and giving up a 1st for Pulj here, neither of which I would be inclined to do. It's close enough value wise, but it's a bad time for Montreal to waste a roster spot on Lucic (taking development time away or sitting better players) and I'd rather not use a 1st on a player that has already had his development and health hampered.
