Quoting: Pierre_from_Orleans
If you don't trade Z for Brass we likely wouldn't have went to the Conference Finals and you don't have Gus or JBD.
After looking at the two Brassard trades in a vacuum more closely, this is how Ottawa did:
Mika Zibanejad
Vincent Dunn
33rd overall pick for 2018
64th overall pick for 2018
for
Derick Brassard's contributions to the Ottawa Senators between July, 2016 and February, 2018
Ian Cole
Filip Gustavsson
22nd overall pick for 2018
83rd overall pick for 2019
194th overall pick for 2018
I would say Pierre Dorion made up for the Zibanejad trade, at least somewhat.
But, you're absolutely right.
I'll erase the Zibanejad trade
