I like the debrusk idea, not sure you get much more than a 1 for 1. Leafs have no use for montour though.

Nope. Can’t see Debrusk being moved for a rental. Maybe RNH, who I doubt is on the market. Beyond that. Nah.

If the Bruins are "going for it". A retained Hall for Debrusk might makes sense for both teams.
Staal to Colorado that's about right
Leafs really don't need Montour now, but some team will,. Yep value is good but Sabres would have to retain to make it work likely.

But some good thoughts.

The leafs didnt want Montour before they signed Brodie, the sure as shoot dont want him now after how awful he's looked and Dubas would think it was a prank call if someone dared ask a 2nd for him

Bruins don’t do this trade unless Hall is sticking around with Boston.

Staal hasnt been very good this year, I wouldnt give a 2nd for him

Staal is probably a third. Doubt he gets you a second and a fourth.
