Phoenix GM is interested in signing him. That doesnt mean he'd join them for the playoffs, in fact there is basically no way they'd bring him in for the playoffs. He'll get a 2-way contract and start out in Texas in the AHL.
Thats no secret, but these claims that he's already signed are stupid unless there from a real source, which since were going on 2 days clearly wasnt a real source. It was speculation. ANYONE can speculate.
