However, the Canucks went out and added Elias Lindholm, regarded as the number one trade deadline acquisition. The Bruins feel like they need to answer and continue to improve their roster.
The Bruins would certainly use him more than a 7th defenseman. He comes with a minimal cap hit, which the Bruins could easily work with and would cost minimal assets which fits perfectly within the Bruins situation.
As a reminder, the Bruins don't hold draft picks in the first three rounds this year, and do not want to use their first rounder next year unless it brings back a significant return.
