Pietrangelo, who signed a seven-year contract Oct. 12, scored 22 power-play points with the St. Louis Blues last season, tied for sixth in the NHL with Victor Hedman of the Tampa Bay Lightning. The defenseman's 6.09 power-play points per 60 minutes ranked sixth at the position among those who averaged at least two power-play minutes per game. His production contributed to the Blues' power-play success; at 24.3 percent, St. Louis ranked third in the NHL behind the Edmonton Oilers (29.5) and the Boston Bruins (25.2) during the regular season. The Golden Knights had the ninth-ranked power play (22.0) but could finish among the top five with the addition of Pietrangelo this season.
