There are better players then those two who have cleared waivers this year. You don't have to go far, Barberio with the Habs.
I understand why the Habs did it, it simply came down to the weak state of the depth chart. They wanted Tinordi's replacement.
In Jersey, they saw Lou claim Corrado off waivers and then keep him in the pressbox most of the year. Beyond him, I don't know who would have claimed Matteau, he's not an NHL player at this point, go check the Devil's forum. I have followed the Devils more then the Habs this year and just about every forward they brought in or up from the minors bypassed him. On a team crying for offence and loaded with injuries up front, he could not stay in the lineup.
Edit: I'll be delighted if he proves me wrong,
