2010-11: Testwuide was arguably AHL Adirondack's top two-way forward in his first season of pro hockey. In 76 games with the Phantoms he was the team's fourth-leading scorer with 18 goals and 21 assists. His +12 plus/minus was second only to Rob Bordson (+13) on an Adirondack team that finished seventh in the East Division and failed to make the playoffs.
2011-12: Testwuide spent his entire second pro season with the Flyers' AHL affilliate Adirondack. Playing primarily a two-way center, checking-type role, he chipped in offensively for the Phantoms with 12 goals and 17 assists and was minus-five with 7 penalty minutes in 66 games. Adirondack missed the AHL playoffs; finishing fifth in the Northeast Division. Testwuide, a restricted free agent, was re-signed by the Flyers to a one-year contract in July, 2012.
Despite being 6'3, 216 pounds, Testwuide does not seem to realize exactly how powerful he is, even though he regularly overpowers opponents. He drives the net hard and his 18 goals prove he can capitalize on some of his chances. Testwuide doesn't have elite skill or speed, but he's a hardworking player who is difficult to play against and can lay out heavy hits along the boards.
