Right, I get that... But it's also important to remember Matteau is still only 21 years old. It would be a mistake to just waive him and lose him for nothing- again, bad asset management. I'd much rather see if the kid can make it work here than just give him away for nothing just to open a roster spot.
I really don't see him having that much value at this stage. At best he is padding on a trade involving another player, like Patrice Cormier.
As has been said in the other thread he doesn't seem like an NHL quality player right now.
