Skating alongside senior Andrew MacWilliam (Toronto) during the Fighting Sioux’ successful stretch run, he scored 5 goals with 19 assists, both career highs, and was +4 with 12 penalty minutes. Three of his goals came on the power play. North Dakota was third in the WCHA and received an at-large NCAA bid after an overtime loss to Colorado College in the WCHA semifinals. The Fighting Sioux defeated Niagara in the NCAA West Regional semifinals before falling to national champion Yale, 4-1.

Simpson is a cerebral defenseman with great hockey sense and instincts. He thinks the game well and plays a smart, economical style. He is somewhat undersized for a defenseman and his skating has been an issue at times. Simpson made a conscious effort to better himself and make his skills more marketable during his college career.
Simpson missed the start of the 2015-16 season due to injury — joining new Edmonton AHL affiliate Bakersfield in mid-November. He continues to be a consistent, no-frills defender in his second AHL season. Simpson's sound positional play make him an ideal candidate as a lower pairing defender capable of playing in all situations. With Edmonton trading away three young defensemen at the trade deadline Simpson may have his best shot at cracking the NHL lineup in 2016-17.
