Mike Knuble is an unrestricted free agent. He was invited to Detroit Red Wings training camp, but the 40-year-old was a longshot to make the team all along and ultimately did not earn himself a contract. He signed a professional tryout contract with the Red Wings and has been playing for their AHL affiliate, the Grand Rapids Griffins, over the last week. But Knuble, as we know, has a history with the Philadelphia Flyers. And if you haven't heard, the Flyers are in pretty rough injury shape right now. They cleared room for a contract spot today. Could that spot go to Knuble?
