Teams continued to get out in front of the NHL trade deadline that awaits on Wednesday with a couple big deals involving top-four defenseman Monday night.

Both Jay Bouwmeester and Robyn Regehr were on the move.

Calgary traded Bouwmeester to St. Louis in exchange for a conditional first-round pick and two prospects. Regehr was dealt by Buffalo to Los Angeles for second-round picks in 2014 and 2015, according to TSN. The deal was contingent on Regehr passing a physical.

With a $6.8 million cap hit that continues into next season, Bouwmeester never seemed like a viable option to me for the Bruins, as I explained over the weekend. Plus, there was little chance of Bruins general manager Peter Chiarelli and his Calgary counterpart Jay Feaster doing a deal after the Jarome Iginla fiasco.

Regehr, who’s scheduled to be an unrestricted free agent this summer, would’ve been a better fit for the Bruins. Of course, if there was even a glimmer of hope Buffalo GM Darcy Regier would deal a player within the division, Boston would’ve had to better the Kings’ offer (and get Regehr to waive his NMC for Boston). That could’ve meant a prospect in addition to picks, and at some point the Bruins wouldn’t want to help out the Sabres any more than the Sabres want to help out the Bruins.

So Chiarelli’s search for help goes on. Florida’s Brian Campbell and San Jose’s Dan Boyle could be defenseman that could help, if Chiarelli is willing to compete in a high-priced market. Several teams are reportedly chasing no-goal-wonder Ryan Clowe of San Jose. The Sharks scratched Clowe for the game against Vancouver Monday night.
