Hall can be waived, Orr is our only enforcer and J. Ward should definitely not be waived... plus, no more claiming guys off waivers! They're there for good reason and never make a difference for the teams desperate enough to take them... remember Toms, Pushor hell, even Orr. It's scavenging and good teams don't do it. When a guy goes on waivers, it should tell every GM to stay away. Krog might prove to be a decent pick up, however.
I don't think we need to pick-up Murray. However, if one wants to go that route for sentimental reasons, trade Hall for a 7th rounder. Or better yet, Rucinsky. You can then waive the Krog-magnon and have Murray.
