Amorosa is still fairly early in the process in terms of development but has the prototypical size and skating ability to one day be an effective two-way defenseman at the NHL level
After originally committing to playing in Hockey East, Amorosa is skating for Clarkson University in the ECAC Hockey league as a freshman in 2014-15. Closer to home than he would have been at either Providence or New Hampshire, he is expected to make an impact as fourth-year coach Casey Jones looks to build on last year's 21-win season and get the Golden Knights back to the NCAA tournament for the first time since 2007-08. Still relatively raw in terms of development he will have time to refine his game, further improve his technical skills, and add bulk and strength while at Clarkson.
