The Boston Bruins and general manager Don Sweeney are trying to pull off one of the biggest trades in the NHL this offseason. 

Sweeney is trying to bring in defenseman Oliver Ekman-Larsson from the Arizona Coyotes. 

The Coyotes captain told the team last week that he would only be willing to accept and waive his no movement clause for trades to either Boston or Vancouver. 

Since then both teams have been working hard to get a deal done. 

With over a week gone by and no trade, Ekman-Larsson is losing patience. 

According to NHL insider Darren Dreger, Ekman-Larsson and his agent have given both teams along with the Coyotes a Friday deadline to get a deal done or he'll be staying in Arizona. 

Do you think Sweeney is going to be able to pull this off?
