ESPN.com has learned NHL general managers will take part in a conference call Monday, when they will try and come to a consensus on the pros and cons of proposing changes to the collective-bargaining agreement that would allow teams to trade players while retaining a portion of a player's salary. The hope is the issue will then get a hearing before the board of governors when they meet Thursday and Friday. Under the current system, many GM's have complained that the possibility of making trades is near impossible because they don't have the option of eating any salary of a player they might like to trade. The move is being spearheaded by Anaheim GM Brian Burke, who believes he will have the support of as many as 25 of 30 GM's. "I'm with Burkie on this. I support his efforts," Tampa GM Jay Feaster told ESPN.com. "I don't understand why it's a problem [to make the change]. I really don't."
