Fowler is an offensively oriented defenseman in the mold of a Scott Niedermayer. He is an excellent skater and puck handler, and his instincts and hockey sense are as good as any defenseman in his draft class. Fowler isn't all offense, however, as his play in his own end is usually solid.
Fowler has developed into a full-time NHL defenseman.
