ANALYSIS
Mattson was selected by the Hawks in the sixth round of the 2010 NHL Draft but never suited up in the majors. A product of the University of North Dakota, the blueliner split last season between the AHL and ECHL where he garnered 22 points in a combined 65 contests. Odds are the 24-year-old will have to land an AHL contract or head overseas to continue his professional career.
