Hauswirth is a tall forward with some goal-scoring capability who can skate and play both center and wing. His energy, size and scoring ability are intriguing assets. He has some decent stick handling skill and is willing to drive the net to create a scoring chance. He is also valuable as a penalty killer.
Hauswirth has been dealt to the Dallas Stars from the Panthers. Hauswirth has the size and two-way mentality of a lower line forward and but still has a long way to go as a prospect. Having played neither major junior nor college hockey, he is learning as he goes through his professional career this far, but at this point, Hauswirth is a long-shot to reach the NHL.
