Labarbera can be better than Cloutier & Garon when he's on his game. His game fell apart last season when his mother died from cancer. But he's back on his game and would be a cheap quality pickup.
His mom didn't die from cancer. His gf got cancer.
The reason why a trade would be good is that the guys you'd want would probably be gone from the waiver wire by the time the Flyers would be able to pick. A trade would allow you to get the guy you want.
