Simpson's size allows him to take up a lot of the net. He is technically sound and controls his movements well, making it difficult for shooters to beat him straight up.
In October Simpson was acquired by the Islanders from Chicago along with defenseman Nick Leddy in exchange for defensemen T.J. Brennan and Ville Pokka and goalie Anders Nilsson. With Jaroslav Halak off to a fast start at the NHL level and minor league veterans Chad Johnson, Kevin Poulin and David Leggio all in the system Simpson has begun the season with the ECHL's Colorado Eagles. His long-term potential remains to be seen.
