The Oilers' defense has not looked this good in at least an entire decade, and team chemistry is at its most cohesive since the 2005-06 Stanley Cup Final run. Even the Taylor Hall for Adam Larsson trade is looking great (addition by subtraction in team spirit and cleaning up the air, adding a quality defensive defenseman, and making room to sign a more physical top-six left winger in Milan Lucic are three huge victory points for Edmonton).
Such a trade would not have been necessary, however, had Colton Teubert panned out as the team expected him to when they traded for him with the Los Angeles Kings (along with first-round and second-round picks, for Dustin Penner). The Oilers took a chance on the 6'4", 210-pound former first round pick (13th overall in 2008) because he'd previously been teammates with Jordan Eberle with the WHL's Regina Pats, making the All-Star Game and having Regina mayor Pat Fiacco proclaim January 8, 2010 as "Jordan Eberle and Colten Teubert Day".
