Real reason Bruins pulled out of Rasmus Andersson trade.

It was a wild week on the National Hockey League rumor mill last week with dramatic reports about a potential Rasmus Andersson trade out of Calgary. As we now know, the now former Flames defenseman was indeed traded on Sunday but not to the team that most expected would land him.

After nearly an entire week of reports that suggested Andersson to the Boston Bruins was all but a done deal, Andersson was traded to the Vegas Golden Knights on Sunday. So where did it all go wrong for Boston?

Well according to NHL insider Elliotte Friedman, it was the Bruins themselves who pulled out of the deal once they learned that things with Andersson had changed.

"On Saturday night, the Boston Bruins believed they could get a deal done with the Flames and there would be an extension," revealed Friedman on the 32 Thoughts podcast. "Everything changed on Sunday morning."

According to Friedman, the Bruins got some new information from Andersson's agent on Sunday morning that completely changed the equation for them.

"Andersson's representative, Claude Lemieux, he called the Flames and he said 'We are willing to go to Boston but we are not willing to do an extension and we won't be doing an extension anywhere right now."

The Bruins offer was contingent on Andersson signing a new deal, resulting in the Bruins pulling out of the deal.

"The world flipped, there was chaos in the streets, everything changed and the Bruins were out," said Friedman.

There were reports for some time that the Bruins had the best offer on the table, which unfortunately for the Flames likely means that they did not get the best deal for Andersson as a result of his unwillingness to extend with the Bruins.
