Amorosa is beginning to display signs of developing into the prospect the Flyers thought they were getting when the drafted him directly out of prep school. He has the prototypical size and skating ability to one day be an effective two-way defenseman at the NHL level and in his two years at Clarkson he has steadily adapted to the college game.
Amorosa continued to make strides in his sophomore season at Clarkson University in 2015-16. A long-range prospect when he was selected by Philadelphia in the 2013 NHL Draft, the Quebec native was the team leader in plus/minus and is an offensive threat from the point. With several talented defensemen in the Flyers' pipeline he could face a numbers game in earning an entry-level deal following his college career. His progress to this point suggests he can be an effective skating defenseman with some offensive push to his game.
