Not only that, but 1g and 3a have come for Toffoli in the last 5 games.
He and Heinen are having similarly bad seasons, but Heinen is younger and will be a lot cheaper going forward.
Toffoli IMO would be a cheaper acquisition than the price Toronto paid for Muzzin.
Compare the two.
Signed for this year and next. Similar cap hits (4.0 and 4.6 AAV).
Muzzin was having a strong season in LA despite the teams struggles. Toffoli is having the worst season of his career.
Muzzin is a D-man, Toffoli a winger. D-men are harder to find/acquire than wingers.
Toffoli doesn't get a 1st round pick out of anyone.
So substitute the 1st rounder they got for Muzzin and call it a 2nd rounder.
Muzzin didn't cost the Leafs a single roster player. So the Bruins wouldn't need to include Heinen. Given their time spent in the NHL, they shouldn't need to include JFK, Bjork, or Donato.
Frederic, Studnicka, and Vaak are A-level prospects IMO and I wouldn't include them.
I'd give them their choice of one of the B-level prospects.
Lauzon
Zboril
Clifton
Andersson
Lauko
Fitzgerald
Senyshyn
Hughes
Then I'd let them take a C-level prospect skater or a later round draft pick like a 4th or 5th.
That's about what he's worth IMO. There is no guarantee that Toffoli's production ever returns to his previous level, so there is some risk to the acquiring team with his cap commitment, hence the price.
