Wouldnt have a pro with Aaron Ward at all. A guy that can step in just in case on injury and can play a PK role as a 5th, 6th Dman. I wouldnt give up anything other then maybe a mid tier prospect or 6th or 7th round pick, but still wouldnt be too bad IMO.
If Murray has kicked the tires everywhere else and the prices are too high, then screw it, just add depth, Ward is a good 7th D man. If we had Lee filling in if/when injuries hit during the playoffs, that would be big trouble. Ward was really good for Boston as of last year, his game hasnt fallen to total crap in that time, he was on a bad team with a bad defense and an awful coach. In Ottawa he would be fine.
