Make no mistake. The power play an oxymoronic term over the last two seasons in which the Rangers ranked 23rd in the NHL with the man advantage in both 2011-12 and 2012-13 is the ultimate responsibility of head coach Alain Vigneault. “The buck stops with me” Vigneault said following Friday’s workout. “I am going to empower [assistant Scott Arniel] on the power play and [assistant] Ulf Samuelsson on the penalty killing a little bit more but I’m the one at the end of the day who is accountable for those situations.” Arniel the former head coach of the Blue Jackets who has a history with Rick Nash Derick Brassard Derek Dorsett John Moore and Anton Stralman watched tape this summer of every one of the Blueshirts’ 197 power plays from last year’s regular season and playoffs. Right: better him than you. Arniel who operated as head coach of Vancouver’s AHL Chicago affiliate last year did not offer a direct critique of last season’s dysfunctional power play that went 4-for-44 in the playoffs. Neither did Vigneault who dropped the convenient “I wasn’t here” card. But in discussing Nash’s role on the five-on-four Arniel implied the overall approach was every bit as faulty as the execution. Indeed the PP was so haphazard the Rangers might as well have worn blindfolds to their own man-advantage executions. “I noticed there were a lot of different looks with [Nash] in a lot of different places” Arniel said. “We’re going to try and get him in the best place possible and more than likely that’s somewhere out in front of that net whether it’s in the high slot or right in front.
